A still from Walt Disney's Tomorrowland.

There weren't as many fireworks at the Memorial Day weekend box office this year as newcomer "Tomorrowland" disappointed with a $32.2 million debut.

The science-fiction adventure stars George Clooney and was directed by Brad Bird of "Mission: Impossible - Ghost Protocol" renown. The Disney release is expected to pull in a lackluster $40.7 million for the four-day period.
