Listen up y'all, a few big motion pictures are set to film in Montreal this summer and that means plenty of celeb sightings! Some are already in production, so when you're downtown (especially in the Old Port) be alert and have your cell ready for potential selfies with the stars.

We've already walked in on a cast catering for the film Stonewall... yes that was quite embarrassing. Initially, we thought it was open auditions for extras, but as it turns out, the cast was already chosen and they were eating what was suppose to be my food.

All that aside, when you see big camera crews, please acknowledge that it's probably not be global news! It's likely a film set and you should get on that ASAP (but don't do anything too rash or you'll risk the wrath of their security).

We've already snagged some pictures of stud muffin Joseph Gordon Levitt but there are many celebs to be on the prowl for.
