Throughout the film when Scott faces an evil ex, a number corresponding to them appears: Evil Ex 1 = Alpha symbol on his shoulders.Evil Ex 2 = 2 on the trailer. 2 on the car. A small tattoo of 2 on his neck. His belt has two X's, XX.Evil Ex 3 = 3 on his shirt. Also 3 on the trash cans in the alley.Evil Ex 4 = Number 4 on the night club door.Evil Ex 5 & 6 = Amp system goes up to 11 (5+6).Evil Ex 7 = When Scott goes to see Gideon it mentions it is level 7.When Gideon makes his sword appear, all of the stats read "x7". He also makes a reference to the gum he swallows to being in his digestive tract for 7 years. The final score after Scott defeats Gideon is 7,000,000,000 Scott himself is seen wearing (and drinking) "Zero" a number of times.
When Scott opens the door to receive his package, Michael Cera actually did throw the package over his shoulder into the bin after 30-odd takes (most of which are seen on the "outtakes" of the DVD). However, the signature shown on-screen was a visual effect superimposed onto the paper.
After defeating Roxy, Scott asks Ramona to give him a list of her evil exes and she sarcastically says that she might have it laminated. A few minutes later, when she actually gives him the list, it is in fact laminated.
Scott orders a caramel machiatto at Second Cup. Starbucks sells caramel machiattos; Second Cup serves caramel corettos. However, this is probably a reference to the graphic novel stating Scott didn't realize until the age of 23 that all Second Cup entrances do not lead to the same interior. Scott probably didn't realize before this that all coffee shops do not have identical menus.
When Scott leaps up and goes to attack Todd across the table, and Todd holds him back with waves of energy, the girl drummer from TCAD is first leaning against the wall, disappears from the frame, and then reappears when the scene shifts. This is most likely a reference to the graphic novel where this character is able to teleport at will. She may be said to have teleported out of this location and then back into it.
Based on the landmarks present within the film (Honest Ed's, Lee's Palace, Casa Loma), the film primarily takes place in and around the Annex neighborhood in the central part of the city. Honest Ed's is a popular department store in the area and is visible in the background of many shots. There really is a Pizza Pizza restaurant across the street (though the interiors are different than seen in the film). Lee's Palace is a popular live music venue and it is located about two and half blocks east of Honest Ed's. Casa Loma is an actual castle located about 3km (1.9 miles) north of both landmarks and can quickly accessed by either subway or bus. There really is a steep staircase that must be climbed to reach Casa Loma from the south. The Annex is also home to The Bloor Cinema, a repertory cinema where Edgar Wright hosted screenings during production of the film. The school used in the film is St. Michael's College School, located at Bathurst St. and St. Clair Avenue West.
