For a few years now, Jillian Bell has been stealing scenes and commanding the screen in a multitude of comedic supporting roles. Now, in her first major leading role, Bell steps firmly into the spotlight and delivers the very definition of a star-making performance.
In Brittany Runs a Marathon, she is the titular Brittany who finds her comfortable but go-nowhere life upended after a doctor's visit brings her weight and life choices into question.
Pushed on by seemingly perfect neighbour Catherine, Brittany reluctantly takes up running. Buoyed by the sudden personal changes, she quickly becomes committed and decides she will take on the New York Marathon.
It's a story that easily could have been played with total seriousness and high drama, but Bell and writer-director Paul Downs Colaizzo instead opt for comedy that allows the themes and story to naturally develop.
Brittany is an awkward but sociable goofball masking a sadder, more insecure self, and Bell showcases the two sides of her character with flawless perfection.
