Back in the 1990’s, I used to make a joke about Kevin Costner, how he seemed to only star in three hour movies in which he got to play some iconic childhood hero. Like he’s saying, “Hey, I’m Robin Hood!” (Robin Hood: Prince of Thieves) or “Hey, I’m a cowboy!” (Wyatt Earp), or “Hey, I’m an Indian!” (Dances with Wolves), or “Hey, I’m Aquaman!” (Waterworld).
Of course, Waterworld is not actually about Aquaman, but some other guy who can swim really fast and survive the depths of the ocean. Part of the joke is that the idea of making an actual Aquaman movie is just ludicrous. Oh, how times have changed.
