But it wasn't just a chance to make it on to Batman's radar. The Japanese-American actor also hoped to open a conversation about diversity in Hollywood.
"This was really just to start that dialogue, and it's clearly done so," he told Heat Vision.
"In the [YouTube] comments, I see time and time again, 'I don't want to see an Asian Tim Drake [the third DC character to take up the mantle of Robin],' and other people go, 'Hey, he's also half-Caucasian.'
"On the other end of the spectrum, I see people say, 'Oh my God, he looks just like him. We need him as Tim Drake.' That's exactly what I wanted to happen."
After googling Tim Drake, Potter noticed he bears a resemblance to the character and "thought it would be absolutely amazing to see an Asian-American face in that cast".
"Marvel has done a really amazing job lately of adding a lot more diversity to their universe. One thing I noticed about the DC universe is it's very one-note at the moment in terms of age and diversity," Potter said.
Very little is known about Affleck's upcoming Batman film - other than that Joe Manganiello has been cast as Deathstroke - and Tim Drake may not even appear in the film.
But if he does, Ben Affleck's got a frontrunner to play him.
