There has been much speculation over Todd Phillips’ anticipated sequel to “The Hangover,” but turns out that not all of it was true. Bill Clinton will not be making a cameo appearance, but Paul Giamatti will play the “bad guy.”

Clinton was reported to have filmed a cameo after meeting the crew, but actor Ed Helms has denied that he did.

Clinton had been spotted on the set with stars including Zach Galifianakis and Bradley Cooper in November.

"Check your sources. He came and visited us. I'd be surprised if there's a scene in the movie," Helms told MTV.com.

Speaking to MTV at the Sundance Film Festival, Giamatti, who is currently starring in “Barney's Version”, said, “I play Mel Gibson…no, I think Liam Neeson plays that. I just did it with the three guys, who were great. They kind of swore me to secrecy. I play a bad guy in it.”

Jamie Chung will also join the cast, replacing Heather Graham as Helms’ character Stu’s love interest.

One thing that we can be sure of is the four main cast members, Cooper, Helms, Galifianakis and Justin Bartha will return, as well as Ken Jeong, who will play the role of gangster Mr. Chow. Boxer Mike Tyson, so popular in the first “Hangover,”  will also return in a cameo role.

The movie is set for release in the U.S. on May 26.
