Who was the actor that flew to Atlanta that same Saturday to help with the screen testings? Thats Robert Downey Jr.. As everyone knows, Downey has a reputation for his talent, charisma in his stunning portrayal of Tony Stark. However he is also known for being relatively short, standing at 5ft 8in tall to be precise. Can you picture the skinny Asa Butterfield (60) screen testing with Robert Downey Jr. (58)? Tom Holland in the other hand is shorter than Robert Downey Jr. (5'7''). While that wasn't the main reason that Holland got the role instead of Butterfield, it certainly didn't hurt Tom's case to look good next to the Marvel Cinematic Universe's main man. Back on June 3rd, when Asa Butterfield posted on twitter #6ftclub four days after the screen-testing happened, he already knew that Marvel and Sony wouldnt need him on set back in Atlanta.
