The Big Lebowski isn't a bowling movie, it's a movie that just happens to be mostly set in a bowling alley.  However, it is also one of the funniest movies you'll ever see, so it gets my vote!

Love Kingpin, yes they didn't neccesarily portray bowling in its most favourable light, but some classic scenes  (When big Ern says 186, you lost to a club player" .

Big Lebowski is truly a brilliant Coen brother's movie, not really a bowling movie, but each scene when viewed more than once is hilarious.. Love Walter, "Fluck it Dude, lets go bowling!", I think though with the Big Leb, they show the love of league bowling.. When Walter screams out "Over the line... Mark it zero Dude, next frame".. Brilliant scene... At the end of the day, the Dude reall only wants to bowl and take it easy, man I wish my life could be a simple as his, although it does get a little chaotic due to his rug lol!!!..Love the fact that the Dude just loves bowling, even listening to casette audio recordings of league bowling at home...  If u haven't seen either of these movies definately worth seeing...There are so many great scenes in this movie.

Trying to get Dreamer on a torrent site, but almot impossible to get..

In my opinion, there has never been a first-class movie about bowling, but I respect other opinions on the subject.
