Harrison Ford's 40th movie, 'Cowboys and Aliens,' was released on Friday. To commemorate the occasion, the National Post's Steve Murray put together 'Forty Fords,' showing Ford in character from each film -- beginning with his first flick, 1967's 'A Time for Killing,' all the way through his new sci-fi picture that opens today.

Take a look to see how many Ford movies you can identify, and then mouse over each illustration on the Post's site to see if you were right.
