Remember seeing this when it was out, but it seems to have disappeared

I remember seeing a TON of movies in 1978 - Foul Play, Corvette Summer, FM, Jaws2, The End, Hooper, Grease,Caseys Shadow, Convoy, Every Which Way But Loose,Same Time Next Year, Up In Smoke, etc. but this one seems to have disappeared. As I recall, I thought "Somebody" was right in line popularity-wise with all of those. It was similar to Foul Play in that the characters were inadvertently involved in a murder, but yet is not remembered at all, but most people know Foul Play.I was very young, but it was the first time I had seen Jeff Bridges, and he seemed to be a future star. I remember the theater was packed, but maybe it was a fluke. About 5 years ago, I got this movie on what looks like a bootleg DVD, but it's fairly legit quality.
