There are four for me:
VON RYAN'S EXPRESS
THE EAGLE HAS LANDED
THE SHINING
GHOST STORY
All four based on books I loved but their film adaptations were a bit 💩
Not so much a remake, but Id like to see some of the special effects in Jaws updated. Not in the quite the same way as Lucas did with Star Wars, but just some more subtle touches here and there, like when the shark rolls onto its side to bite a swimmer.
MANOS, THE HANDS OF FATE. Great idea and atmosphere, but terrible execution. Also, not many movies had the balls to show that ending. I would love to see a fully-fleshed Torgo with proper goat legs.
