Anachronisms: When the family go to the telephone box to phone Nazir, a train passes in the background. The movie is set in 1971, and the train carries a color scheme (Intercity) that was not introduced until the mid-1980s.
Continuity: When Nazier runs away from the wedding there's a shot of Tariq without his hat on, yet the next shot shows George with Tariq behind him removing his hat.
Anachronisms: As the family enter Bradford they cross a sleeping policeman, but these were not seen on British streets in the early seventies.
Continuity: In the first shot of the house, we see two photos hanging above a mantel. The distance between the photos increases between shots.
Crew or equipment visible: When the Khan family set off for Bradford in the van, a very large camera crew of about a dozen people are visible, reflected in the van.
Boom mic visible: In the scene when they are in Bradford, Ella and her daughter are in the kitchen. Ella comforts her friend because she is upset about her daughter in Pakistan. In the background on the painting on the wall you can see the reflection of the boom mike as it goes up.
Continuity: When Meenah kicks the ball through Mr Moorhouse's window at the Enoch Powell poster the ball hits slightly right of Powell's head but in the next shot the hole is conveniently dead-centre.
Anachronisms: When the family enter Bradford they run over speed bumps which wouldn't be around in the 1970s.
Factual errors: During the open scenes of the parade, there is a marching band with a group of associated uniformed children. These are all members of the Church Lads' and Girls Brigade. However, the uniforms on camera weren't introduced to the organizations until around 20 years after the film is set. Also, the organizations didn't exist until 1978, making it impossible for them to exist in the film.
Factual errors: During the opening scene of the movie a short introduction of George Khan is given as an immigrant who migrated to United Kingdom from Pakistan in 1946. In fact Pakistan was formed in August 1947 as a separate state from the newly independent India.
Anachronisms: Terraced housing in Salford would have had sash windows back in 1971/2. Only one house had them in the shots.
Anachronisms: The lamp posts are too new for 1971. It is possible that most side streets were still gas lit with ornate cast iron poles or with smaller concrete posts.
