The entire film KIND HEARTS AND CORONETS is a monument to irony. Almost every scene in it is a study in irony.
This thread immediately becomes a textbook case in current ignorance in what "irony" means.
R1, for example, does not understand the difference between farce with a black edge and "irony." KIND HEARTS AND CORONETS lacks any trace of irony except in its framing and ending, but one would hardly call a de rigueur comeuppance at Mazzini's self-paid expense a fine example of irony.
For R1, a link. Sorry about the big words in it, dear.

Agro - the scene where Afleck is told "you can teach a monkey to be a director". Actually, Ben's whole character is ironic as he directs the hostages how to behave, etc.
The Joker calls Maggie Gyllenhaal "beautiful", I think?
The final scene of "Dangerous Liasons" as Glenn leaves a crowded theater with rejection and tears.
