Jeremy Piven: Neeson's a nice guy

Jeremy Piven wants people to know Liam Neeson doesn't really have "a very specific set of skills that's going to kill anyone".

Liam has become known as one of Hollywood's leading hard men over the past few years, thanks to his roles in the Taken franchise and flicks like Run All Night.

He is one of many stars to have a cameo in the eagerly-anticipated Entourage movie, where Jeremy reprises his role as Ari Gold, and was great fun on set.

"He's one of these guys who's so brilliant and yet willing to make fun of himself. He pulls up in a convertible Bugatti. It's just like, you know, Liam Neeson's this guy from Dublin [he was born in Northern Ireland] who's very humble and sweet and he's not the guy that has a very specific set of skills that's going to kill anyone. He's like a nice thespian, you know'" Jeremy laughed to US talk show host Seth Meyers.

Although he takes his craft seriously, Liam was only too happy to get stuck in on set. That led to his scene going swimmingly, with Jeremy happy to discuss what's in store.

"And yet he's so self-deprecating and as he pulls away I yell - because I try talking to him and he just goes, 'F**k off already,' and pulls away - and I'm like, 'Schindler! Leave no Jew behind! Schindler!' And he's just gone," the actor giggled, referencing Liam's Oscar-nominated role in 1993's Schindler's List.

"He doesn't care. But that's the great thing about people when they do a cameo with Entourage, they're selfless. They make fun of themselves and we have a blast."

Many stars have got involved with the upcoming project, which also sees main stars Adrian Grenier, Kevin Dillon and Kevin Connolly returning. The cameos were confirmed when a trailer for the film was released earlier this week, with the likes of Jessica Alba, Pharrell Williams, Calvin Harris, George Takei, Tom Brady, Kelsey Grammer and T.I. all appearing.
