With the theatrical release of Doctor Strange in the Multiverse of Madness now in retrospect, new information about the film’s development has come to light. As it turns out, screenwriter Michael Waldron Reed Richards originally wanted to be in the film for a post-credits sequence in which the character discusses footage of the film’s events. During the sequence, the person viewing the footage displayed stretching forces – not unlike those of Reed.
In fact, Waldron recently opened up about his original plans to bring Reed Richards into the Marvel Cinematic Universe. Of his plans to have him in the sequel (via Empire), Waldron said, “I always wanted Reed Richards in this thing. In my very first draft, just for fun, I wrote a tag about the events of the film being recorded and reviewed by someone in the Baxter building, and a stretchy hand coming in to render it. Reed is probably my favorite Marvel Comics character, so I’ve always wanted to put him in here somewhere.
Based on the description of how the sequence would have played out, it is unclear if the scene would have revealed the actor playing Reed in the sequence. Had that element been kept secret, it would have allowed Marvel to quickly roll out the concept of Richards without casting anyone – similar to how Strange was mentioned but not shown in Captain America: The Winter Soldier.
