I caught the first few minutes of this this morning and have my doubts of the claim that Charlie Sheen was supposed to play the murder victim in flashbacks but couldn't because he had to go shoot Platoon.
The reason I think this is inaccurate is because The Wraith is actually a (loose) remake of Clint Eastwood's High Plains Drifter, which also uses the mechanism of a vengeful ghost who looks similar to how he looked in life but is played by a different actor.
Also, did anybody else notice how many people in this movie are related to more famous people?
-- Charlie Sheen (Martin)
-- Nick Cassavetes (John)
-- Randy Quaid (Dennis)
-- Clint Howard (Ron)
