He may not be saving the world like his character in the Transformers franchise, but Shia LaBeouf is making his own mark as a comic book cartoonist.
LaBeouf, 25, has drawn and written his own graphic novels, Stale N Mate, Cyclical and Let’s Party, and the webcomics series Cheek Up’s, all sold through his self-publishing website.
The actor even surprised attendees at the Chicago Comic and Entertainment Expo last weekend by purchasing a table to sell his books and sign copies for fans. LaBeouf, who went largely unrecognized, says the best part about the impromptu trip was just “having an opportunity to blend in with 5,000 fans all enjoying the same thing.”
