Nov 1 (Reuters) - DreamWorks Animation SKG Inc's third-quarter results beat analysts' estimates, riding t he international box office success of ``Madagascar 3: Europe's Most Wanted''.

The company said Madagascar 3, which released in June, raked in nearly $720 million worldwide, of which 70 percent was from international markets.

DreamWorks' last movie for 2012, ``Rise of the Guardians'', featuring the voices of Alec Baldwin, Hugh Jackman and Jude Law among others, will release on Nov. 21 in the United States.

The company expects fourth-quarter results to be driven by that film as well as the continued international success of Madagascar 3 and its home video release.

The animation studio behind the hugely successful ``Shrek'' and ``Kung Fu Panda'' franchises said net income rose to $24.4 million, or 29 cents per share, in the third quarter, from $19.7 million, or 23 cents per share, a year earlier.

The company, which competes with Walt Disney Co's Pixar among others, said revenue rose 16 percent to $186.3 million, a quarter of which came from Madagascar 3. 1/8I D :nPnLA04544 3/8
