Avengers: Infinity War Directors Reveal How Thanos Knows Tony Stark

Thanos and Tony Stark have more in common than an Avengers: Infinity War fan might initially realize, which is why the writers and directors gave them intimate lines of dialogue in the film's third act.

On the commentary track of Avengers: Infinity War's digital download, co-directors Joe Russo and Anthony Russo and screenwriters Christopher Markus and Stephen McFeely opened up about the connection between Thanos and Tony Stark. When the Mad Titan bested Tony Stark in combat on Titan, he revealed he was "burdened with knowledge" like Stark and promised the earthbound tech genius had his respect.

"The journey that Tony's been on as a genius scientist is that the evolution of his armor. This is the best it's ever gonna get for Tony and it's nanotech," Joe Russo said. "He goes to the cutting edge of what his mind can deliver, and it still is not enough to beat Thanos. In fact, it barely keeps him in the fight."

The development of Tony's armor and his growing necessity to protect the world (as has been on display, especially in films like Avengers: Age of Ultron), make Thanos and Tony similar in their ideas of building a future, though their solutions are drastically different.

"You realize this interesting parallel between Thanos and Tony," Markus said. "They're both aware of something from an early point and constantly having to deal with being smarter. Thanos is a futurist as much as Tony Stark."
