ET’s Thea Andrews catches up with Tom Cruise in Berlin, Germany, where his movie ‘Valkyrie’ is set to premiere this week.

Tom says he is very excited to be debuting his film in Germany, where the star said there had been some initial trepidation because of the subject manner.

In ‘Valkyrie,’ Tom plays Col. Claus Graf von Stauffenberg, who helped hatch a plot to assassinate Adolf Hitler at the height of World War II in order seize power and put an end to the bloodshed.

Tom describes the film as an “important story” he couldn’t wait for audiences to see and says the movie still keeps him on edge every time he watches it.

He also reveals to Thea that his most crucial item while on the road is his BlackBerry, which allows him to get constant messages and photos from his wife Katie and daughter Suri back home.
