Paul McGann(I)

He was originally cast as the lead in the ITV's "Sharpe" series of television movies but ruptured a cruciate ligament playing football a few days into the shooting of Sharpe's Rifles (1993) in the Ukraine. Due to a misdiagnosis he continued for weeks, unwittingly causing more damage. He was replaced in the role by Sean Bean, who starred not only in Sharpe's Rifles (1993) but the other thirteen films as well. Bean's replacement of McGann triggered the largest insurance settlement in British television history...a value of £2,128,172.

[on his one-off performance as the Doctor in Doctor Who (1996)] I don't want to be remembered as the George Lazenby of Doctor Who.
