Marlon Wayans was supposed to be Robin in "Batman Returns"?!!!?

From the “Batman Returns” wikipedia:

The studio desperately wanted Robin to appear in the film. He was originally supposed to appear in the original film, though Burton and Hamm convinced Warner Bros. otherwise. Waters found writing the character very hard, because “Tim and I personally hate him, he’s just the most worthless character in the world, especially with Tim’s conception of Batman as the loner of loners.”^[2] Waters had visioned Robin as the leader of a street gang, though before he was written as an African American, to which he forms a “hard-edged” relationship with Batman.^[2]Batmobile after Penguin wrecks it. Waters quoted that the costume was to be “an old-fashioned garage mechanic uniform and it just has an ‘R’ on it.”^[2] There was also to be a scene where he drives the Batmobile in the same manner he does in Waters and Burton argued that there were too many characters in the script and then visioned another version of the character. He was then written as an intelligent African-American working in an autoshop garage. He was to supposedly fix the Batman Forever, which Waters feels, “they [the writers of Batman Forever] ripped me off! They didn’t even give me free popcorn for that!”^[2]Marlon Wayans was cast in the role and was even paid with a contract of two films. He was initially cast in the role for Batman Forever but Wayans later said, “They decided they wanted somebody white,” which would turn out to be Chris O’Donnell. Wayans was paid for both films without having to do any acting.^[9]
