Elvis & Brando?
Hardy appears to be acting as Brando. Butler as Elvis (obviously) and James Dean. So this looks like if you ever wanted to see those guys in a Wild One, Rebel Without Cause type movie (the type of movies Elvis wanted to be doing when he started out in Hollywood) with all the iconography of the Americana of the era (probably a heavy dose of Easy Rider too)
The director did that 80s Spielberg homage Midnight Special so this probably be like that for the stuff I mentioned
