To paraphrase Mr. Big’s 1992 song To Be With You:
“Waited on a line of greens and blues”
As of June 23, 2019, Avatar and Avengers: Endgame are the first and second highest grossing films of all time, respectively. Avengers: Endgame headed back to the theater with unreleased footage in effort to unseat Avatar.
Whether or not the attempt is successful, both films have the same name in the casts: Zoe Saldana.
She was blue in Avatar and green in Avengers: Endgame.
One more note, both 20th Century Fox (distributor of Avatar) and Marvel Studios (Production company of Avengers: Endgame) are subsidiary of Walt Disney Studios.
