St. Louis Post-Dispatch columnist Joe Holleman has an item today about my cameo in an upcoming poker road movie, “Mississippi Grind”…

STL radio host/poker power Paul Harris will have his mug on the big screen next month, when he has a cameo in “Mississippi Grind.”

The movie opens Oct. 2, and stars Ryan Reynolds and Ben Mendelsohn, who play itinerant gamblers on a road trip. It is written and directed by Anna Boden and Ryan Fleck (who gave Ryan Gosling his break in “Half Nelson”).

Harris said he met with the pair in 2011, when he was doing a poker show on radio with Dennis Phillips, the St. Louisan who finished third in the 2008 World Series of Poker.

Harris is on-air on KTRS every Friday from 3-6 p.m., and also fills in on a regular basis.

“I told them a bunch of stories about playing poker, and playing in house games, and they said a couple of those ideas would probably be in the movie,” Harris said.

After several fits and starts, filming began in early 2014 in New Orleans. Harris ended up being cast as a featured extra who goes head-to-head with Mendelsohn.

“I don’t have a line,” Harris said, “because if you say a line, they have to pay you more.”

I’ll have much more to tell you about the movie — and my experience on the set — in coming weeks, but before it hits theaters, if you have DirectTV, you can watch “Mississippi Grind” on-demand right now.
