The director of the Anchorman sequel, The Legend Continues, Adam McKay has praised Kanye West's performance in the film.
Word broke that the rapper was appearing in the Will Ferrell comedy when he was spotted on set last month with his partner Kim Kardashian.
In an interview with MTV News, McKay said: "He was great, and he was funny. He came up with a couple of good lines on his own.
"We did our usual style of do the written line, and then I would throw out alternate lines and we'd improvise. He was completely cool and game."
He added: "He even showed up for an extra quarter of a day where he had no speaking lines.
"He was just kind of in the group fight sequence, and he was having so much fun that he came back to do that."
