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 y sus fusileros (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 y sus fusileros (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.
