A bit like using the names of comic book writers, or your favorite teacher in High School to fill creative gaps in secondary characters, sometimes you need a date for an event in a film and you want it to mean something. Then it makes sense to reach for a date that is important in real life.
That’s exactly what happened in Avengers: Infinity War when we find out the date of Tony Stark and Pepper Potts’ wedding. It’s August 27th, which is actually an important date to Robert Downey Jr. It’s the anniversary of his wedding to his wife Susan Levin. They were married in 2005, so we think this is a pretty cute tribute.
