Travis Bickle from Taxi Driver
Well, I've never seen the movie, but to fulfill a request that sounded like an interesting challenge, here is Travis Bickle (played by Robert De Niro) from the movie Taxi Driver.
More great reader-submitted stuff today as well, including the 3rd Doctor with his Bessie and 10th Doctor in "Voyage of the Damned", sent in by Cliff (click images to see bigger)
Also, an awesome Spartacus (Andy Whitfield) from Ximo! Nice work!
