Has anyone heard about releases of 50s detective shows like Hawaiian Eye,
77 Sunset Strip, The FBI, Bourbon Street Beat, State Trooper, etc.?
I tried to contact Warner Brothers, but they don't bother to reply.

Yes, the names 77 Sunset Strip and The FBI are familiar, but all I can remember is the opening to The F.B.I. with the shield and F...B...I coming on the screen....maybe I am confusing it with Dragnet.

Don't forget Surfside 6, the third of WB's trilogy of hip detective shows that aired concurrently, Hawaiian Eye and 77 Sunset Strip the other two. So far WB has expressed zero interest in these shows. Same with their westerns, Bronco, Sugarfoot, Cheyenne(we got a little of this one) and the big daddy of their 50s shows, Maverick.

Darn, well I guess the only recourse is Sell.com

Yeah, and how about Highway Patrol, Mr. Lucky and Peter Gunn?
