In an interview clip late in the movie, the head stock of Jimi's Strat is clearly visible. It isn't a Fender that Jimi would have used, but a Suhr, a brand of Superstrat that began production in 1997.
In a scene where Jimi is meeting with record producers, a shot of a city street shows late model cars. A black SUV can be seen driving from left to right of screen.
