As you may have noticed, the Tesla Roadster made an appearance in the first Iron Man movie. The association has continued, deepened slightly even. In Iron Man 2 Tesla Motors CEO Elon Musk makes a cameo appearance as himself.

This isn’t the first time Musk has been involved in a Hollywood film as he was a producer on Thank You for Smoking in 2005 and as well as new film coming out this year called Dumbstruck.

But what is most interesting of all is the impact Musk had on the Iron Man script, simply by being who he is. When Iron Man Director Jon Favreau confided in lead actor Robert Downey Jr. that he had no idea how to make the main character, genius billionaire Tony Stark, real. Downey told him, “We need to sit down with Elon Musk.”
