To determine which of the sentences is incorrect, we need to identify any grammar or punctuation errors.

a. The sentence "The movie, which was over two hours long, kept me on the edge of my seat" is grammatically correct. The use of commas to set off the relative clause "which was over two hours long" is appropriate.

b. The sentence "The movie, that was based off of a novel, kept me on the edge of my seat" contains a grammatical error. Instead of using "that," it should use "which" to introduce the relative clause concerning the movie being based on a novel. Corrected, the sentence would be: "The movie, which was based off of a novel, kept me on the edge of my seat."

c. The sentence "The movie that we saw was over two hours long" is grammatically correct. The use of "that" to introduce the relative clause is appropriate.

d. The sentence "The movie, which kept me on the edge of my seat, was based on the director's favorite novel" is grammatically correct. The use of commas to set off the relative clause "which kept me on the edge of my seat" is appropriate.

Therefore, the incorrect sentence is b: "The movie, that was based off of a novel, kept me on the edge of my seat." The correct version of this sentence would be: "The movie, which was based off of a novel, kept me on the edge of my seat."
