S1 E5: He's had a meteoric rise to fame in the '80s, co-starring with fellow Brat Packers Molly Ringwald, Demi Moore, and Charlie Sheen in a series of popular teen movies. After scandals and controversies threatened to derail his career, Lowe got back on track and officially took his career off life support when he joined the cast of The West Wing. His role in the TV hit earned him his third and fourth Golden Globe nominations, two SAG awards, and an Emmy nomination.
