There are certain perils to working alongside Snoop Dogg - and Matthew McConaughey learned them first-hand, as he revealed in a new interview with Jimmy Kimmel.

McConaughey and the rapper are starring in Harmony Korine's forthcoming film 'The Beach Bum', and during filming it seems that things got a little... strange at one point. Mostly because Snoop swapped the fake 'prop' marijuana that was to be used in one scene for real marijuana.

He told Kimmel that his character, Moondog, visits Snoop to procure some 'magic weed' to help his writer's block, and that he checked with the prop department to ensure that it was not real weed.

"I went to the prop man to make sure I have the prop weed which is like crushed oregano,” he said. “We pass back and forth and all of sudden at the end he goes, ‘Yo Moondog, that ain’t prop weed, that’s Snoop Weed.’ I was like, ‘Oh you son of a a gun.'”

 

He added: "The next 9 hours were a lot of fun but I don’t think we used one word in the English language.”

'The Beach Bum' is set for release later this year.
