Execs at TLC, the cable net that brings you the Gosselins, Sarah Palin and Sister Wives, know a good thing when they see it -- and they're looking straight at Charlie Sheen, Breaking Celebrity News has learned.

Charlie Sheen: On the Brink is the title of a one-hour documentary that's been rushed into production, according to The Hollywood Reporter.

The show will feature video from the former Two and a Half Men star's recent media blitz -- primarily from NBC -- a co-producer in the venture, and will include what is being billed as "expert commentary" from MacKenzie Phillips who has considerable first-hand knowledge of what it's like to be a celebrity with a drug problem.
