In an interview with The Big Issue (via Uproxx), the 93-year old Lee spoke about the potential of a Star Wars and Marvel crossover. After all, both universes are currently owned by Disney, so it is theoretically possible. And Lee seems totally okay with this thoroughly outrageous concept:
If they feel that incorporating Star Wars with the Marvel characters will be very successful, they’ll find a way to do it. Can you imagine Spider-Man saying, ‘May the force be with you?’ It may come to that!
But let’s not dismiss Mr. Lee too quickly. After all, he does point out that the Avengers only came about after he threw a bunch of disparate characters together. So why not add the cast of Star Wars to the mix:
I created the Avengers by taking many of our characters and making a team out of them. We can have as many characters join the Avengers as we want to for future movies. That might be fun, all of a sudden Luke Skywalker is an Avenger!
