Very good film
Watched it today (received the video on Saturday) and I think it's one of the more unsung '70s thrillers. Bill Cosby was outstanding as the downtrodden Hickey and Culp was just as praiseworthy as his loyal partner. Just witness their scene together in the bar after Hickey's wife dies. Excellent.
Like others, I'll say the story was a bit confusing. I felt no empathy at all for Mary Jane and her husband. Michael Moriarty was good as a particularly vicious bad guy.
The film also boasted three awesome action sequences. The pulsating football stadium shootout, the car park confrontation and the explosive finale on the beach.
I read somewhere that Culp actually re-wrote Walter Hill's original script and when he saw the final product, Hill wasn't very pleased. Maybe Hill wrote some scenes that had to be deleted or put some more humour into it. Culp once said that without H&B, there'd be no 48 HRS.
They should have done a sequel to this. Maybe it could have been called just HICKEY, therefore only focussing on Bill Cosby. They could have had him as a lone troubleshooter, along the lines of The Equalizer, with Robert Culp back at the helm.
