William Petersen, best known as Gil Grissom in CBS's procedural smash "CSI: Crime Scene Investigation," was never a prolific screen actor. Deadline.com once called him "one of those highly selective actors who never wore out his welcome."

He seemed to take that to extremes with "CSI." He was so concerned with wearing out his welcome that he left the show early, and then mostly dropped out of the screen biz in favor of theatrical acting back in Chicago, where he got his start.

And that's mostly "what happened" to Petersen. He's taken a total of five screen roles since leaving "CSI" in 2009, and when he wasn't doing those he was busting a hump on a Windy City stage.

If you really miss hanging out with Petersen and you aren't fortunate enough to live in Chicago, I have two pieces of good news: One of his other screen gigs was a full-time TV role you might not have heard of (the WGN America drama "Manhattan"), and "CSI" might be coming back.

He appeared in all 10 episodes of the second season of the period military drama "Manhattan" in 2015 -- it was canceled after that, but you can still find it if you look.

But you could also just be patient and wait to see whether the planned "CSI" revival goes ahead, and, if it does, whether it includes Petersen.

Back in February, rumors started swirling that a "CSI" revival miniseries would happen on CBS. There's still no official word on it, nor which, if any, of the cast will return.

The plan was reportedly to time it with the show's 20th anniversary in October. The clock's obviously ticking on that, but the "CSI" team was always good under pressure.
