You're right Annie,it was Speilberg's debut and personally I think it was way too good to be just a made for TV film.
It's on been on DVD now for about 2 years,I still want to get it because I never get tired of it.
I watched those same shows Jess.

Starsky & Hutch/The Rockford Files/Hawaii Five 0 (also new on DVD S.#1)/Baretta/S.W.A.T. etc....
Kojack & Charlie's Angels are currently being rerun on the "ION" TV network (formerly PAX and/"I". (Channel 51 here in AZ).
Getting back to Malden,I was quite impressed with his acting in "A Streetcar Named Desire" which also starred Marlon Brando & Vivian Liegh.
It wasn't until IMDB that I realized how long he'd been around.

I hop he makes it to 100.
