This film along with Donnavan's Reef are my favorite movies of all time. It's just a fun movie! The characters and the locations are simply wonderful. I never tire watching it.

John Ford did a wonderful job with this movie, I liked how he got family members of not only the cast be even some of the crew into the movie, the geezer kiltimabar mentioned was actually John Ford's brother, Francis. That is a hilarious scene when Father Paul is praying for him and he suddenly gets up and runs out pulling up his pants as he is chasing the fight.
I think that the big fight has to be one of the favorite fights in film of all time, everybody I talk to about this movie that always comes up. One of my favorite scenes is the morning after the wedding when the conspirators show up with Mary Kate's belongings, still drinking singing that wonderful waltz:

It was there that I learned all me courtin’
Many lessons I took in the art
Till Cupid, the blackguard, while sportin’
An arrow drove straight through me
Mush, mush, mush, tural-i-addy
Me mush, mush, mush, tural-i-ay

So I lathered him with me shillelagh
For he trod on the tail of me
Mush, mush, mush, tural-i-addy.
And just like the Dingle for gold,
I lathered him with me shillelagh
For he trod on the tail of me coat.

ahhh now that had to be a wonderful night of drinking with your friends!!!
