Hanks: Being a movie star is easy!
Tom Hanks says turning his hand to directing has been much more gruelling than being a film star.
As well as co-writing the script and directing the movie, the Forrest Gump and Toy Story star plays the eponymous hero in Larry Crowne.
Speaking about going behind the camera for the first time in 15 years to direct a film, he joked: "It's like you have to be infected with a certain type of E.coli that takes you over until you're like, 'The only thing I can do now is direct a film', because it's two years of your life.
"Quite frankly, being a movie star is a much better gig.
"It pays better, you don't have to work as hard and they let you go home early sometimes - directing requires a personal investment in telling a story."
Tom first went behind the camera as director of Sixties-set comedy That Thing You Do!, which he also wrote and starred in.
His new film is the story of a Navy veteran who gets fired from his job at a superstore and goes back to college, transforming his image and falling for his disillusioned teacher, played by Julia Roberts, along the way.
The star said: "The trick is making a movie that doesn't turn out to be the most depressing film you have ever seen."
