Parents need to know that The Sparks Brothers is a warm and engaging documentary about the band Sparks, with some strong language, archive footage depicting violence, and a brief reference to drugs. Directed by Edgar Wright (Hot Fuzz), the film features interviews with Californian brothers Ron and Russell Sparks -- best known for the 1974 hit single "This Town Ain't Big Enough for Both of Us" -- as well as a whole host of other celebrities, including Beck and Mike Myers. The movie is a highly positive celebration of the brother's music and their integrity, influence, and individual style. The brothers are an enjoyable presence both musically and personally. Early on they talk about losing a parent at a young age. Infrequent strong language used by interviewees includes "f--k" and "s--t." A bloody head wound is recreated on a clay model. Archive footage from movies occasionally has brief violence scenes. But these are used for cultural context or as metaphors for the band's story. Archive footage also infrequently shows people drinking alcohol and smoking cigarettes. An interviewee mentions "having a beer" and Flea from the Red Hot Chili Peppers briefly talks about an experience on drugs. A member of the same band appears in a photograph with a sock on his genitals and another man's bare bottom is show in archive footage. A man performs a striptease wearing woman's clothes in an old music video.
