Please Kill Mr. Know It All

To celebrate 6 weeks of hard work, the executives purchased a large cake for the crew on the last day of photography. The cake was being stored in the production office, which, unbeknownst to special effects supervisor Jamie Sled, was equipped with a video surveillance security system. When co-director Colin Carter went to retrieve the cake at the end of the day, all that he found in its place was a sheet of paper colored in with crayons to crudely resemble the original cake. Upon reviewing the security footage from earlier that day, Sled was clearly visible on camera committing the swap. Despite extensive effort by the production to locate and prosecute Jamie Sled, he has never been seen since and it is assumed that he fled the country. Due to the underlying circumstances it is now assumed that Sled was also a ringleader in the notorious 'cookie bandit' case.

There are multiple thematic shots in the film that prominently display startled pigeons flying out of frame. The 23 pigeons used for these shots belonged to Director of Photography Pasha Patriki, who in his spare time adopts and trains picture pigeons from his home in Toronto.

A permitting error at the City of Toronto Film and Television Office resulted in the production being issued a road closure permit that coincided with the Toronto gay pride parade. Production vehicles were parked the night before and paid duty officers manned the set overnight, but when crew showed up on Sunday July 3, 2011, they were greeted by crowd control barricades and thousands of parade goers there for a completely different event. The Supertechno crane parked at the intersection of Yonge and College the night before is visible in many official Toronto Pride photographs. Production manager Joe Alonzi was quoted as saying "This is a force we can't reckon with, cancel the shoot".

During filming, the "apartment set" had a scene where a grenade was to be tossed through the set window by Special Effects Technician Stephen Van Allen and then thrown back out by actor Jefferson Brown before triggering a debris cannon to simulate the grenade explosion. While in any other conditions, having the grenade land in the debris cannon's funnel would be an impossible shot, Jefferson Brown's tosses landed the grenade in the funnel each and every time. It took 11 takes before getting it right and triggering the debris cannon. This cannon along with more than 250 bullet hits and squibs destroyed the film set in its final scene.

During filming, large special effects debris cannons were used to simulate the blast from a grenade outside the "building". A delay in Production resulted in the special effects team waiting for an extended period of time. Out of boredom and hopes to get filming again, the FX team told director Colin Carter that the cannons were outfitted with a self-purge mechanism and that after 20 minutes of idle time they would erupt and send debris all over the set unless a reset button was pressed. They expressed that they could only reset this 3 times, making 60 minutes the max wait time. Needless to say, Production was back up and running in a jiffy! The gag was revealed later that day to Colin.
