Screenshot: YouTube You can never have too many superheroes, especially if they’re played by Melissa McCarthy and Octavia Spencer. The duo are teaming up on-screen in the action comedy Thunder Force to play best friends Lydia and Emily, respectively, who turn into unlikely crime-fighting heroes for their city and battle villains like The King, played by a smarmy Bobby Cannavale.

Lydia visits Emily at her place of work and accidentally gains super strength while messing around with gadgets she was clearly instructed not to touch. Emily also possesses her own power: invisibility.
