In the scene where Tim and Mike are stuck in traffic, which parodies The Sixth Sense (1999), the angry cyclist they've knocked over is played by Olivia Williams, who had a role in that film.
During the ending credits, Tyres is seen stuck on the crossing outside 156 Hammersmith Rd., Hammersmith, London W6 7JP.
Movie reference: Mike's daydream when asked how they might get Tim's portfolio back is a reference to the famous lobby gunfight scene from The Matrix - complete with the same song that plays there, "Spybreak" by Propellerhead.
As Knox comes out of the lift, Tim falls backwards into Mike's arms, parodying Sarah Connor's reaction in Terminator 2: Judgment Day (1991) as Arnold Schwarzenegger's Terminator comes out of the hospital lift.
