Dumb and Dumber mistakes
Continuity: When Lloyd tackles Mary on the hotel stairs, she is wearing black pantyhose. By the time they get to the hotel room, she has miraculously changed into grey tights.
Visible crew/equipment: When Lloyd is daydreaming about Mary as the doors to Mary's house open and Lloyd picks up Mary. He lifts up her skirt to show a little flesh, in the background you can see the feet of two crew members laying on the ground holding the doors open.
Dumb and Dumber trivia
I think that this may be an in-joke. If Mary Swanson had chosen Lloyd instead of her fiancee and married him she would become Mary Christmas.
Jim Carey really has a chip in his tooth. For the filming of Dumb and Dumber he had the cap on his tooth removed.
In the bar scene when Lloyd leaves he sees the newspaper clipping on the wall and says "No Way! We Landed on the moon?" and walks out, that wasn't originally in the script, Jim Carrey just improvised that line and it was left in the movie.
