Warren Beatty, Alec Baldwin, Hayley Mills and Richard Roundtree join roster for TCM Classic Film Festival

Oscar-winning actor and filmmaker Warren Beatty, Emmy-winner and Oscar nominee Alec Baldwin, Oscar-winning actress Hayley Mills and Golden Globe-nominated actor Richard Roundtree have joined the growing roster of special guests for the 2011 TCM Classic Film Festival, taking place in Hollywood April 28 through May 1. The festival will also include two films starring legendary actor Gregory Peck, introduced by the late actor's family and his "To Kill a Mockingbird" co-star Mary Badham; world premieres of the 50th anniversary restorations of "Breakfast at Tiffany's" (1961) and "The Guns of Navarone" (1961); a special screening of the groundbreaking musical "Cabin in the Sky" (1943), introduced by film historian and author Donald Bogle, whose latest book "Heat Wave: The Life and Career of Ethel Waters" has just been released; and recently re-discovered gems such as the long-unseen "The Constant Nymph" (1943).

Baldwin, who starts his third season co-hosting TCM's "The Essentials" movie showcase with Robert Osborne March 5, is set to interview Beatty as the prelude to a 30th anniversary screening of "Reds" (1981). Mills will be on-hand to take part in 50th anniversary screenings of "The Parent Trap" (1961) and "Whistle Down the Wind" (1961), the latter based on a novel by her mother, Mary Hayley Bell. Roundtree is set to present a 40th anniversary screening of the landmark blaxploitation flick "Shaft" (1971), the film that earned him a Golden Globe nomination for Most Promising Newcomer.

The family of Oscar winner Peck will pay tribute to the late actor with two screenings, including the world premiere a new restoration of "The Guns of Navarone" (1961), which celebrates its 50th anniversary this year. They will be joined by actress Badham to introduce Peck's Oscar-winning performance in "To Kill a Mockingbird" (1962), in which Badham played Peck's daughter.

In addition to the 50th anniversary world-premiere restoration of the romantic comedy-drama "Breakfast at Tiffany's" (1961), the festival will feature the world premiere of the 35th anniversary digital restoration of the Clint Eastwood western "The Outlaw Josey Wales" (1976), as well as a 35th anniversary screening of the Paddy Chayefsky-penned "Network" (1976).

Three major musicals have joined the lineup as part of a multi-faceted celebration of movie music: the landmark African-American musical "Cabin in the Sky" (1943), introduced by film historian and frequent TCM contributor Donald Bogle; the Oscar-winning "West Side Story" (1961), presented in 70mm in celebration of the film's 50th anniversary; and "Pennies from Heaven" (1981), writer Dennis Potter's nostalgic musical marking its 30th anniversary.

The festival's celebration of movie music will also feature a salute to composer Bernard Herrmann in honor of the 100th anniversary of the composer's birth. His work will be the focus of a 60th anniversary screening of "The Day the Earth Stood Still" (1951), a 35th anniversary presentation of Martin Scorsese's "Taxi Driver" (1976) and a screening of the fantasy classic "The 7th Voyage of Sinbad" (1958). A salute to Roy Rogers, in honor of the 100th anniversary of the singing cowboy's birth, will include screenings of "Under Western Stars" (1938), "Cowboy and the Senorita" (1944), "My Pal Trigger" (1946) and "Trigger Jr." (1950).

Among many rediscovered gems added to the festival lineup are the long-out-of-circulation romance "The Constant Nymph" (1943), a frequently requested film that earned star Joan Fontaine an Oscar nomination; "The Devil is a Woman" (1935), one of seven collaborations between actress Marlene Dietrich and filmmaker Josef von Sternberg; and the pre-code comedy "This is the Night" (1932), Cary Grant's first feature film role. They join such previously announced rarities as "Went the Day Well?" (1942) and "Night Flight" (1933).

For night owls, "Film Forum" programmer Bruce Goldstein will cue up a screening of William Castle's horror gem "The Tingler" (1959), complete with several surprises in keeping with Castle's reputation as a master of promotional gimmicks.
