Brittany Runs a Marathon
Simply put, Brittany is a piece of work — a funny piece of work. Brittany is quite capably played by the delightful and funny Jillian Bell. She drinks a lot, parties too much, is not the best employee at the theater, and is not living her best life. When Brittany seeks medical help in hopes of getting a prescription for drugs, instead she gets told to exercise and lose some weight. Like many people who start an exercise program, it's a struggle to get started. But for her, the biggest struggle is that of her mind.
She's not quite happy with her life, job, or relationship prospects. The real foe in this chick flick is Brittany herself. She's held by back by her own lack of accomplishment and stale existence, but she has everything a girl who wants to change needs — the desire to and a good crew. Among them, her brother in law (Lil Rel Howery) and her presumably perfect neighbor (Michaela Watkins). Her love interest (Utkarsh Ambudkar) is a far cry from Mr. Perfect but their wonderful banter is fun to watch. This film works because it's about someone you can identify with - the average, working American woman trying to carve out a decent, rewarding career and life. You can recognize Bell as your neighbor, friend, or co-worker who's oftentimes funny and sometimes unlikable (as we all can be when our mouths get running too much). Brittany is an earnestly genuine character thanks to the talents of Bell and a solidly written script.
