It’s time to celebrate the Sundance Kid. Multitalented matinee idol Robert Redford was born on Aug. 18, 1936, making this the actor, director and famously handsome gentleman’s 85th birthday.

If Redford, a native of Santa Monica, California, had stuck solely to acting, he’d still have a legendary career. He began his career in the world of theater, making five appearances on Broadway by 1963. His fifth, Neil Simon’s comedy "Barefoot in the Park," would lead him to stardom on the screen as well as the stage.

Redford’s role in the 1967 film adaptation of the play catapulted an already-promising career onto a much higher plane. In the decade that followed, he went on to star in "Butch Cassidy and the Sundance Kid," "The Candidate," "The Way We Were," "The Sting," "Three Days of the Condor" and "All the President’s Men," just a few of the many films he’s anchored since "Barefoot" made a splash.

But Redford became a force to be reckoned with behind the camera as well, particularly as a director. He made his directorial debut with — and earned an Oscar for — the 1980 drama "Ordinary People," starring Donald Sutherland, Mary Tyler Moore, Judd Hirsch and Timothy Hutton

Yet with all those incredible movies on his resumé, one could argue that Redford’s greatest accomplishment is one that has dramatically impacted the world of film and will continue to do so for years to come: the creation of the Sundance Institute and the Sundance Film Festival

Since its foundation in 1981, the Sundance Institute and Film Festival have made an incalculable contribution to moviemaking, helping remarkable independent filmmakers to find their audience and premiering many movies now considered contemporary classics, such as "Little Miss Sunshine," which made a splash when it debuted at the festival in 2006. 

With a career like that, there’s nearly always more to discover. Put down the Wonderboy bat and experience some of the lesser-known titles from Redford’s career, all streaming for free on Tubi.
