Saw this on cable about 100 years ago it seems, picked it up recently for $5 and found it entertaining enough. This was, I think, a vehicle for "The Hudson Brothers," an all-but-forgotten 70's musical group, tho they're hardly in this, and that's a good thing. They make the Bee Gees in "Sgt. Pepper" look intelligent as they try for "3 Stooges" laughs in this light comedy/actioner.
Worth the second look: Sylivia Miles as a hard-as-nails car repo hag, just- divorced McGavin as a befuddled, bumbling "everyman" caught up in a whirlwind of odd characters/events after his ex takes everything he has and Denise Nickerson, aka "Violet" from Willy Wonka as a tough-but-sweet juvenile. Too bad she quit the biz early on, she was fun to watch. Interesting cameos by Joan Collins and Gordon MacCrae(Curly, from Oklahoma...???!!!).
More amusing character study than laugh-out-loud comedy, a little ugly to look at and Nickerson wanting to sleep with McGavin seemed creepy. If you re- member "Corvette Summer" and liked it you'll probably like this...if you can find it...
