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 in a screen test for a new late-night television program called Saturday Night Live. He got the part, of course, and his star rose rapidly along with the show's. 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). But sadly it all came crashing down 30 years ago this month--on March 5 1982--when he died of a drug overdose. In this clip we remember the young Belushi: cocky, talented, with a brilliant future ahead of him.
