It's that time of year again. Thousands of international leaders from all walks of life are expected to descend on Davos in the snowy Swiss mountains, to discuss the latest global issues.
At the World Economic Forum's annual meeting, the main theme up for discussion will be "Responsive and Responsible Leadership"; which seems fitting, especially as a new U.S. president will be sworn in during the week of the event.
While President-elect Donald Trump is expected to be a key topic among leaders, who will actually be in Davos to discuss such topics?
With around 3,000 leaders from politics, finance, business and science expected to attend, CNBC takes a look at just some of the top names expected to make an appearance.
Having been a regular Davos attendee, International Monetary Fund Managing Director Christine Lagarde will be weighing in on the state of the global economy at this year's meeting.
According to the WEF program, Lagarde will be participating in at least three panels, covering the world's economic outlook, gender roles and fixing the "middle class crisis." You can also be sure she'll be asked to comment on Brexit, Europe's economy and globalization.
In December, Lagarde was found guilty, convicted on negligence charges over a state payout made during her time as the finance minister of France. Despite the conviction, she was not punished and kept her post at the IMF.
After OPEC and non-OPEC producers agreed to cut output at the end of 2016, all eyes will be on leading oil chiefs to see if countries stand by the deal and can fix the current global supply glut.
One energy chief expected to attend is Khalid al-Falih, Saudi Arabia's energy minister. Being one of the world's top oil producers, the country will be a big part of the conservation at Davos. One topic al-Falih is expected to comment on is that of Saudi Arabia's Vision 2030, and the country's decision to diversify itself away from its oil dependency.
The "fourth industrial revolution" may have been last year's theme for Davos, but it doesn't mean that technology's power and its disruptive nature isn't still a big topic for 2017. Fake news, the use of social media and new technological innovations are expected to be part of the discussions at Davos.
One of the leading figures in the tech space is Sheryl Sandberg, chief operating officer at Facebook.
Having commented on technology at previous WEF events, this January, Sandberg will be participating in a discussion with Hewlett-Packard Enterprise CEO Meg Whitman on "A Positive Narrative for the Global Community". Sandberg will also be sitting down for a conversation entitled "A Leader's Resilience".
When he's not busy filming, Hollywood star Matt Damon devotes a large part of his spare time doing humanitarian work. Subjects in which the actor is particularly passionate about include the water crisis, fighting hunger, and advocating for global human rights.
In 2014, Damon told an audience at Davos that having traveled in Third World countries he "started to get a real appreciation for the magnitude of the water crisis, " a crisis he found shocking.
At Davos 2017, Damon will continue with the discussion of water, participating with fellow Water.org co-founder, Gary White on a panel covering sanitation access and finding solutions for delivering fresh water worldwide.
It may be the week Donald Trump gets sworn in as the next U.S. president, but one event outgoing U.S. vice president Joe Biden isn't going to miss is WEF's annual meeting in Davos.
At Davos in 2016, Biden spoke to audiences about LGBT rights, cancer treatment and employment welfare, according to Reuters. In recent days Biden has spoken out about his future, with the Associated Press reporting that Biden said he intended to pursue his "cancer moonshot" agenda after leaving the White House, which would look at how the U.S. conducts its cancer research and development.
Central bank policy could also take center stage in 2017, with many market-watchers focusing on how leading financial institutions will react to events, such as Brexit and Trump's presidency.
The European Central Bank's Benoît Coeuré, a member of the executive board, will be attending the forum. The bank will also be delivering its latest policy decision next week, due out on January 19.
Members from other central banks going to Davos, include those from the financial institutions of France, Brazil, Kenya, Japan and the U.K.
China's economic condition was on the minds of many at last year's Davos, however this year a key topic is what Trump has planned for future relations between the U.S. and China.
President Xi Jinping will be attending this year's meeting at Davos — the first time a Chinese head of state will attend WEF in Davos. While it is yet to be seen whether the president will talk about globalization, the yuan or Trump; these topics will definitely be up for discussion around Davos this month.
Shakira will be promoting the work of her "Barefoot Foundation" organization, which helps vulnerable and impoverished children though quality public education.
One year ago, Davos painted the U.K. in a very different light. One year on, however, the snow has settled and Brexit is happening.
One leader expected to weigh in on this topic is that of British Prime Minister, Theresa May. Aside from May, other U.K. politicians that are attending include Finance Minister Philip Hammond and Mayor of London, Sadiq Khan.
It's not just the U.K. who is expected to have their say on Brexit at the annual event. Eurogroup President, Jeroen Dijsselbloem – like many other European leaders – has in the past stated that the U.K. cannot "cherry pick" profitable parts of the European Union as it negotiates its departure from the political-economic bloc.
Yet Brexit might not be the only topic up for discussion, with Dijsselbloem having previously weighed in on Europe's economic state, Donald Trump and Greece's debt crisis.
The European Commission's Pierre Moscovici and Valdis Dombrovskis will also be in attendance.
Like Matt Damon, when Forest Whitaker isn't taking Hollywood by storm, he's spending a great deal of time fighting for important causes.
As a social activist, Whitaker has contributed to a number of projects including founding the "Whitaker Peace & Development Initiative", which looks at helping conflict-hit communities rebuild and prosper into safer societies.
The actor is expected to take this message of peace to Davos this year, with Whitaker participating in a chat on "The New Lead Characters" and "An Insight, An Idea with Forest Whitaker".
