Rare footage from 1975, a 26-year-old John Belushi just days before SNL

In this rare footage from 1975, a 26-year-old John Belushi warms up with some eyebrow calisthenics before doing his signature Marlon Brando impression just days before his debit on a new late-night television program called Saturday Night Live. By 1978 Belushi could boast of having the number one late-night television show (SNL), the number one movie (Animal House) and the number one musical album (The Blues Brothers’ Briefcase Full of Blues).
