James Belushi's older brother was a comedy darling in the late '70s thanks to the still resonant Animal House and his scene-stealing position in the Saturday Night Live cast. An arguably unstoppable reign was just beginning when he was found dead at the Chateau Marmont, having overdosed from taking a Speedball, a combined injection of heroin and cocaine.
