Hollywood leader Jack Valenti has announced his retirement after four decades lobbying for the film industry.
Valenti headed the film lobbying group for almost four decades
He will be replaced as president of the Motion Picture Association of America (MPAA) by Dan Glickman, a former Democrat agriculture secretary.
Mr Valenti, 82, has been the face of the Hollywood movie industry for 38 years, breaking new ground in copyright protection and anti-piracy laws.
Mr Glickman was chosen by seven major studio heads after a long search.
A Harvard-educated Texan, Mr Valenti has been in the public spotlight since 1966, when he took over the MPAA leadership.
A former Army Air Corps pilot, he rose to prominence in 1963 when he was a witness to the assassination of US president John F Kennedy and was subsequently employed as a special assistant to the White House.
While MPAA president, he established the voluntary film rating system to replace an outdated censorship system.
Announcing his retirement, Mr Valenti said: "It's been a long ride and a great ride, but it's time this great adventure comes to an end."
Mr Glickman, 59, served in Congress from 1978 to 1994, including two years as head of the House Intelligence Committee.
His most recent post was as director of the Institute of Politics at Harvard University's Kennedy School of Government.
He was chosen from among 25 potential candidates for MPAA post, which reportedly pays more than $1m (£547,000) a year.
Mr Glickman said: "It's going to be a hard act to follow."
