I see few films, it doesn't mean much that I haven't seen this one.
Looked it up on imdb website.

Freddie Highmore, whose career has brought him to US network television,
has a part in this film.

I imagine the two senior actors
made a meal out of the dialogue
between two lifelong enemies.
Actors are so enthusiastic about playing parts
that in real life are perilous situations. As in:

did I hurt you, darling, when I killed you?
