TMZ has video of Matthew McConaughey dancing on stage with Jimmy Buffett for the upcoming film The Beach Bum:

The Oscar-winning actor’s in Miami shooting for his upcoming film, “The Beach Bum” … and showed off his groovy moves while Buffett played his hit song, “Volcano,” during one of the scenes.

McConaughey plays a rebellious stoner named Moondog in the Harmony Korine film, and judging by the vid … Moondog’s in paradise when Buffett’s rocking out.

“The Beach Bum” comes out in 2018.

In the same Instagram post that Buffett revealed Mac McAnally’s heart attack, Jimmy Buffett shared a photo of himself with Snoop Dogg on a boat in Miami and revealed that he’ll be Snoop’s songwriting partner in the upcoming film ‘The Beach Bum’:

“No, I am not the beach bum in the movie,” Jimmy says. “He is played by Matthew McConaughey. I am JB, Snoop’s writing partner. Movie is directed by Harmony Korine. Coming soon to a theatre near you!”

OK, by now, most folks have heard about Mac's heart attack, which was a little more serious than a Big Mac attack. He is fine now and stable and should leave the hospital tomorrow, which is great news for all of us. Sadly he will not make the hurricane benefit this Sunday in Tallahassee, but while I was working on the set of "The Beach Bum", in Miami on Tuesday, Snoop said he would try and work up "Little Martha". I will keeep you posted on his progress. No, I am not the beach bum in the movie. He is played by Matthew McConaughey. I am JB, Snoop's writing partner. Movie is directed by Harmony Korine. Coming soon to a theatre new you! Fins Up. JB #ginnjuice #dogg #snoop
