Johnathan Southworth "John" Ritter (September 17, 1948 – September 11, 2003) was an American actor, voice over artist and comedian, perhaps best known for playing Jack Tripper and Paul Hennessy in the ABC sitcoms "Three's Company" and "8 Simple Rules," respectively. Don Knotts called him the "greatest physical comedian on the planet." Ritter's final films "Bad Santa," "Clifford's Really Big Movie" and "Stanley's Dinosaur Round-Up" were all dedicated in his memory.
