Actor Kevin Spacey is having a fun-filled time shooting for "Horrible Bosses 2" as the cast, including Jason Bateman, Charlie Day and Jason Sudeikis, makes everyone laugh their hearts out while they were "riffing" and "improving".

The 54-year-old actor says the sequel of the 2011 film "Horrible Bosses" is "a little bit crazier" than the original, reports showbizspy.com.

"I'm very glad that almost everybody is back for it and I so love working with Jason and Charlie because being opposite them in a scene when they're riffing and they're improving and they're trying different ways to do scenes, it is the hardest thing in the world not to absolutely lose your cookies," he said.

`We spend most of our time laughing and any time somebody wants to pay me to come and laugh all day long, I'm there."
