What is the most obvious "they ran out of budget" moment in a movie?

I'm thinking of the original Dungeons & Dragons film from 2000, when the two leads get transported into a magical map. A moment later, they come back, and talk about the events that happened in the "map world" with "map wraiths"...but we didn't see any of it. Apparently those scenes were shot, but the effects were so poor, the filmmakers chose an awkward recap conversation instead. Are the other examples? via /r/movies https://ift.tt/GgYcIol
