Josh Gad is perhaps best known for playing LeFou in Beauty and the Beast and Olaf in Frozen, two lovable characters who are nothing like the villainous Oswald Cobblepot.
With so many Bat-verse films supposedly in the works, it seems entirely likely that the actor could play The Penguin in at least one of them.
Josh Gad could look truly chilling as the character, and if his continued teases are merely a campaign on his part, they’re not a bad way to get people talking about him in the role.
Batman’s rogues gallery and Bat-family are rich enough to support an entire cinematic universe completely divorced from the main DC film universe, so the character is bound to show up sooner or later (he was teased in Justice League, after all).
