Consider the following argument: "Christopher Nolan should win best picture this year. After all, last year he had a great film and he wasn't even nominated." What fallacy does this argument commit?

Appeal to pity

Explanation:

This is the fallacy committed when pity or a related emotion such as sympathy or compassion is appealed to for the sake of getting a conclusion accepted. The speaker here was trying to bring emotions into the argument so he can have some leveling ground in the argument, saying he had a great film last year and wasn't even nominated was intended to strike some emotions so he can leverage on the to drive home his argument.
