C. Thomas Howell
After making his film debut in Steven Spielberg's E.T., Howell was chosen by Coppola to star in this adaptation of the popular young adult novel, The Outsiders, which made him a teen idol in the 1980s. He would go on to star in the films The Hitcher, Red Dawn, Secret Admirer, and Soulman. He has continued to work with Francis Ford Coppola in various capacities, as a screenwriter, producer, and director. Howell grew up in Hollywood, and he secured his part as Ponyboy after believably smoking a cigarette in front of the audition panel.
Rob Lowe
Rob Lowe was an unknown when he was cast, but would go on to become a star following The Outsiders. Previously, he had only been in a TV film called Thursday's Child, for which he was nominated for a Golden Globe Award. Later he would star in the popular teen film St. Elmo's Fire with Emilio Estevez, and the two would be known as prominent members of the "Brat Pack." While he also acted in theater and with more serious work, as a young man Rob Lowe was a teen idol, idolized for his good looks and his roles in movies such as Oxford Blues and About Last Night.... Later in his career, he has found success as a television actor, with roles on The West Wing, Brothers and Sisters, Parks and Recreation, and Code Black.
Patrick Swayze
Like Lowe, Patrick Swayze was also a teen idol, and his role in The Outsiders was his breakout performance. Having already starred as a replacement for the role of Danny Zuko in the Broadway revival of Grease, Swayze was skilled at playing a good-hearted greaser. Following The Outsiders, Swayze starred in Red Dawn, Uncommon Valor, Dirty Dancing, Ghost, Point Break, To Wong Foo, Thanks for Everything! Julie Newmar, and Donnie Darko.

Diane Lane
Like many of her co-stars, Diane Lane's role in The Outsiders was her breakout performance. Having made her debut in A Little Romance and graced the cover of Time, Lane was beautiful and poised, perfect for the role of conflicted but good-hearted Cherry Valance. Later she would star in A Walk on the Moon, The Perfect Storm, Unfaithful, Under the Tuscan Sun, Cinema Verite, and Trumbo. For her performance in Unfaithful, she was also nominated for the Golden Globe and the Academy Award. She is also an accomplished stage actress.
