Shia LaBeouf writes his own comic books. The Indiana Jones and the Crystal Skull actor has drawn three comics, Stale N Mate, Cyclical and Let's... Party, and last week bought a table at the Chicago Comic and Entertainment Expo to sell his work and autograph copies for fans.

"I just did it for fun. I had some downtime and I've always been a big fan of comic books. I've said it's like singing in the shower. It's very free and without edit," he said.

Of attending expo, he added the best thing was "having an opportunity to blend in with 5,000 fans all enjoying the same thing."

However, Shia - who is currently filming two movies, The Company You Keep and The Necessary Death of Charlie Countryman - has no plans to give up acting and take up his hobby full time: "I do love acting. But this is a fun escape once in a while."

Shia is also prepared for any knockbacks or criticism he may get, after having to take a few blows to his ego since becoming an actor: "In my short career, I remember wild blowback from the worst kinds of people you can get blowback from: Your heroes. If you can imagine meeting Superman, hanging out with Superman for a couple of years, and having Superman wake up one day and go, 'Nah, man, you're a f***ing a**hole,' that checks you in a way no parent or circumstance can. It was humbling, and remains humbling, but it's also completely freeing."
