Jeremy Samuel Piven (born July 26, 1965) is a three-time Emmy- and Golden Globe-winning American actor.

Piven's first significant role was as a regular castmember for several seasons on HBO's The Larry Sanders Show, where he played the head writer Jerry. Piven has appeared in several successful films, including Lucas, Grosse Pointe Blank, Singles, Very Bad Things, The Family Man, Black Hawk Down, Heat, PCU, Old School, Guy Ritchie's latest outing Rock N Rolla and Runaway Jury. He also had brief cameo appearances in Rush Hour 2 and in the US release of Cars.

Since 2004, Piven has reinvigorated his career by playing a fast-talking, acerbic Hollywood agent Ari Gold in the HBO series Entourage. He received Emmy nominations for best supporting actor four straight years from 2005 to 2008, and won the award in 2006, 2007, and 2008. 2009 was the first year in which he didn't receive an Emmy Award nomination for his work on Entourage. Piven was also the star and producer of the short-lived ABC dramedy series Cupid, and was a supporting cast member on the last three seasons of the sitcom Ellen. He played the part of Ellen's cousin, Spence. He also voiced Elongated Man in three episodes of Justice League Unlimited.

In 2007, Piven appeared in the video for "Drivin' Me Wild", the third single taken from rapper Common's seventh album Finding Forever. The two were co-stars in Smokin' Aces, and appeared together when Piven hosted SNL in January 2007.

Piven, who grew up in Chicago, performed "Take Me Out to the Ball Game" during the seventh-inning stretch at Wrigley Field on Father’s Day, 2006. Piven gave the cue to Chicago Cubs fans by saying, "Let's hug it out, you little bitches", a line he made famous as his character Ari Gold on the hit HBO show Entourage. The Chicago Tribune reported that he was to have said, "Hug it out, Cubs fans".  He apologized on WGN-TV, and later claimed it was an accident during an appearance on The Tonight Show with Jay Leno.[citation needed] Piven claimed, on The Tonight Show with Conan O'Brien, that the Cubs management had asked him to say his catch phrase from Entourage, and that they weren't familiar with his catch phrase when they asked him.

Piven also appeared in local television advertisements for Cincinnati Bell Telephone, a subsidiary of Cincinnati Bell, Inc. He ended each commercial with the tagline, "Welcome to Cincinnati Bell". These advertisements ended on February 28, 2007, as the rights ended on that date. Piven's voice can be heard in national television advertisements for the restaurant Buffalo Wild Wings, in which he delivers the phrase, "Buffalo Wild Wings: You have to be here". He also appeared in Paul Westerberg's "Dyslexic Heart" video for the movie Singles, and played a balding Michael Barth playing George Costanza on the Seinfeld episode "The Pilot".

Piven was in a series of 1998 TV commercials for the Chicago Blackhawks, including one in which he famously proclaimed "Detroit Sucks!" from the upper level of the United Center. He hosted Saturday Night Live on January 20, 2007 with musical guest AFI. Also in 2007, Piven appeared as Deputy Chief of Mission Damon Schmidt in The Kingdom. He lent his voice to Earth Hour in a video for a campaign urging people to turn off their lights for one hour on March 29, 2008.

Piven appeared in the first Broadway revival of David Mamet's Speed-the-Plow, co-starring "Mad Men" star Elisabeth Moss and three-time Tony nominee Raul Esparza. The production began preview performances on October 3, 2008, and opened on October 23, 2008; the play was due to run through February 22, 2009. After Piven missed several performances, on December 17, 2008, Piven's rep announced that due to an undisclosed illness, Piven would be ending his run in the play effective immediately. The illness was revealed to be hydrargaria, a disease caused by exposure to mercury or its compounds, though the source is unknown. Rumours have indicated that the high level of mercury could potentially have been caused by Piven's excess habits of consuming sushi several times a day. Mamet joked that Piven was leaving the play "to pursue a career as a thermometer".  William H. Macy and Norbert Leo Butz replaced Piven in the Broadway show.

Piven was set to host WWE RAW on August 3, 2009 a week after Shaquille O'Neal, which was shown live on USA Network.  Piven and Dr. Ken turned heel by turning on John Cena and siding with Cena's Summer Slam opponent, Randy Orton and were attacked by Cena for that reason. (via Wikipedia)
