Though nothing has come of it, as far as I know, Von Miller announced back in 2019 that he would be working on an animated comedy TV show about playing football on Mars. The team would be called “Mars Martians” (as creative as “Houston Texans” or “Football Team”, which is probably the joke) and Miller would get to unleash his creative side on the world.
Presumably, working in Hollywood is still something that interests Von Miller, both in the future and the now.
Back in 2016, months after doing more to help the Denver Broncos win the Super Bowl than arguably the greatest quarterback of all-time was able to do that year, Von Miller was the subject of an ESPN interview being conducted at his Hollywood mansion.
