Arrival is a great answer.

By "intelligent" I assume you mean that the writers were intelligent not that the character in the movie was intelligent? It's easy to make a character intelligent. I assume the answer would be the that blue guy from watchman or Jesus or something.
I'm more impressed when the writing is smart. So not Good Will Hunting or anything like that. I think Inception, Silence of the Lambs, Jackie Brown, 6th Sense, 12 Monkeys, and Fight Club are all good examples of smart scripts.
