Please Help - Movie Triva/character question

I have this image growing up of a scene I saw on the tv. Years later this scene still 'haunts' me. It wasn't a scary scene, I just have never been able to place where the image was from. I feel like it MAY be this movie.
This is what I remember:
A scene with a carriage approach a building. Victorian type setting. There is a character who opens the carriage door dressed in victorian type clothing, but has the head of a FISH! Or maybe its that the fish headed looking character was a doctor in this scene?! I'm not sure! Can anyone help? Does this sound like a scene or image from this movie. I know years and years later that my memory may have distorted what happened in the scene, but this is what I can recall that has been haunting me and I just want to find the answer.
It was a live-action (not animated film) with a 'sci-fi' type feel to it.
Thank you for your help
Cheers
