Plummer's character Reikle is not "Harry" but "Frank".
To clarify - the end credits only name him as Reikle and someone here gave him a first name "Harry" which I never hear in the movie. Meanwhile, in the scene where he has attacked the girl, you hear someone first say "Jesus Frank. You almost killed her." , then Freddie remarks "You've gone too far this time, Reikle."
As such his first name should be changed to Frank. Note that I put a correction in for the "Safety Deposit Box Woman" (Nuala Fitzgerald) to be "Mrs. Skinner" which Miles to refer to her as in the final scene. OTOH, if we are going with pure original credits only, then I should have left it and Plummer's character should be renamed to Reikle alone.
Plummer's swearing makes my wife and I laugh - not something we think of with him (e.g. performing Shakespeare and all). We always watch this and Die Hard around Christmas.
