Richard Roeper writes on www.suntimes.com- The last time I saw David Carradine, he was puffing on a cigarette and suggesting we go out and find a bar.

A bit unusual, given that we were in a radio studio and it wasn’t yet noon.

I was doing a guest bit on Erich “Mancow” Muller’s show. This was before Mancow signed on with WLS-AM. He was doing a syndicated show from a studio in the Loop.

When I walked in, Mancow was behind the control board, and there were about a half-dozen other folks behind guest microphones, including local director Adam Rifkin (“Look”), porn star Ron Jeremy — and Carradine, who couldn’t have cared less about any nonsmoking rules.

They were all there promoting a film titled “Homo Erectus,” directed by Rifkin and featuring Jeremy as “Oog” and Carradine in the dual role of “Mookoo/Uncle Unky.” I was there to promote a book about conspiracy theories.

At one point, Mancow was doing a live read or throwing it to news — some official bit of business — but Carradine just kept talking to me, on mic. “I usually don’t like critics, but you’re OK,” he said, or words to that effect. “We should find a bar.”

We never did find that bar and I never did see “Homo Erectus” — but I’ll bet not even Carradine saw 80 percent of all the movies and TV shows he did.

The Internet Movie Database lists no fewer that 13 roles for Carradine on films or in TV shows for 2009 alone, from “Crank: High Voltage” to “Night of the Templar” to “Money to Burn” to “Six Days in Paradise.”

The obituaries for Carradine inevitably mentioned “Kung Fu” and his titular role in Quentin Tarantino’s “Kill Bill” films. Great work, but we shouldn’t forget “The Long Riders,” “Bound for Glory,” “The Serpent’s Egg,” “Death Race 2000.”

….We still don’t know what happened to Carradine in that hotel room in Bangkok — though the reports are getting funkier by the minute — but how odd that four of his 2008 films were titled, “Last Hour,” “My Suicide,” “Death Race” and “Hell Ride.”
