Clifford the Big Red Dog (2000 TV series)
John Ritter voices Clifford in every episode. By the time the series ended production and the subsequent film Clifford's Really Big Movie was completed, Ritter was back on ABC's prime time schedule, starring in 8 Simple Rules. Ritter's death on September 11, 2003, came less than two weeks before the debut of Clifford's Puppy Days (it is often mistakenly cited as the reason the spin-off was created in lieu of a third season).
