I just saw "Dying Room Only" for the first time in over 30 years, and this is a typically great 70's TV-movie thriller. A couple (Cloris Leachman looking pretty good, and hubby Dabney Coleman) stop at a lonely desert cafe (in the daytime, not the nighttime as the summary here states) and the husband disappears as the wife is in the ladies room. The only two possible witnesses (the cafe cook and customer Ned Beatty, in a great sleazy role) are saying nothing. What happened? Where did the husband go? The movie then takes off to have Cloris Leachman trying to figure it out, since she is getting almost no help at all from anyone. Is even the local cop in on it, whatever "it" may be? Everyone is suspect. Nighttime comes, and danger looms....
I do agree with the reviewer that stated this film could have been better in the second half. The first half is amazing - very suspenseful and thrilling. The second half kind of veers into "typical" fare but is still decent.
A bunch of familiar 70's faces round out the small cast. Especially since the film is fairly short at about 1:13 (most TV-movies back then were 90 minutes with the commercials) this is definitely a fun watch.
