The Pit and the Pendulum
The colorful flashbacks, the beautiful settings, the delicious revenge, and you got Vincent Price as well. Directed by Roger Corman and Matheson doing the screenplay. And of course, let's not forget this is a Poe story. This is so good especially as the ending comes. Reminds me of House on Haunted Hill (1959) and if you remember that ending then you know what I am talking about. Definitely worth seeing as it checks off so many like boxes in my book.
