Brad and Eric's apartment was filmed in Room 722 at University College, at the University of Manitoba. This was the exact same room that Geoff Trubiak lived in during his first year of university, 12 years prior to the movie shoot.
No fire trucks were scheduled for the movie - but due to a temperature change on a hot August day, the fire alarm triggered a false alarm, resulting in real firemen and fire trucks responding. Taking advantage of the photo opportunity, Tyhr Trubiak changed into his topless fireman costume, sprinting past the real firemen and surprised bystanders, to get pictures with Leanne Veale beside the fire trucks. The firemen were very good sports about the whole event and were amused by the coincidence.
