Here are some more `wedding` movies to add to your list:
'The In-Laws'  with Alan Arkin and Peter Falk
'True Love'    one of Annabella Scoria's first movies--got to love the
               mashed potatoes dyed to match the bridesmaids' dresses!
'The Clock'   an old Judy Garland movie about a woman and a soldier getting
              married while he is on leave....they've known each other for
              about 3 hours when they decide to tie the knot.
'Blind Date'  Kim Basinger and Bruce Willis, not a great movie.
 If I think of any more, I'll let you know.
