Fake slow motion shot with 5D

Hey guys,
I made a film a few months back that made use of "fake" slow motion using the 5D mark ii. We had the actors act out the punch in slow motion and sped up certain parts of it in post - I think it turned out pretty good after adding some sound effects!

Let me know what you think!
