Never seen it... googled bus driver, cop, dying, movie and came up wtih this.....
http://www.imdb.com/title/tt0100604/usercomments "Burt Simpson, a police detective, mistakenly learns he's dying of a rare disease, but his estranged wife and family will not get the life insurance unless he dies in the line of duty. Throughout the movie he goes extreme with his police work to carry that out. Who knew that veteran character-actor Coleman could pull off such a action-oriented role? He is excellent at both the comedic and dramatic scenes, unlike many actors who perform in this genre. He also has great chemistry with Matt Frewer who plays his partner Ernie. (Burt and Ernie, ha ha!) There is much characterization that we don't often see in action movies.
The circumstances of his false knowledge are very funny. Everyone's reaction to why the hell he is doing this extreme stuff is hilarious, especially after the hostage crisis. This plot does begin a burnout towards the very end, but at least its a short enough movie that it didn't get idiotic. And keep an eye out for what might be one of the most spectacular movie car chases ever. I truly think it ranks up there with "Bullit" and "The French Connection". As for the movie poster, well, lets say it should have shown something different.
Short Time is an action movie with terrific acting, a meaningful story, and top-dollar action. There hasn't been one like that in a Long Time."
