If you’re a Mike fan just from Challengers, you might not know that he actually originated the role of Connor Murphy in Dear Evan Hansen while it was off-Broadway. Although his costar from the theatre production, Ben Platt, signed on to reprise his role in the musical movie, Mike refused to return. The movie ended up flopping horribly, and Ben suffered the brunt of the backlash, with audiences saying he was too old to be playing a high schooler.
