I solved the whole thing and I don't fully get it either! The entry that gave me some insight was 33A33ADustin Hoffman film ➜ Dustin Hoffman, for one *[---]: "Rain Man" is the film, and with the water removed (here, RAIN) it becomes just MAN33ADustin Hoffman film ➜ Dustin Hoffman, for one *[---], which fits the second half of the clue. But I couldn't figure out the other theme entries, so I'd appreciate the explainer too!
