It's a second entry on our list for Ben Affleck, and this time it's for completely different reasons. Everyone knows 'Gigli' as being the 'Bennifer' movie - the film that he and Jennifer Lopez made during the time they were dating. They also know it for being utterly terrible, and crashing miserably at the box office. It made back less than a tenth of its budget, and stalled the acting career of Lopez completely. Affleck was lucky it didn't have a worse effect on him.
That alone would be reason enough to dislike it, but for Affleck, there's more to it than that. He points out that everyone makes bad films occasionally - and that Angelina Jolie had released a bad one a few months earlier - but everyone paid more attention to 'Gigli' because he and Lopez were in it together. That took it from being a bad movie that nobody cared about to a bad movie that everyone wanted to criticize, leading to a miserable time for the actor.
