Theo Germaine first caught the acting bug as a child when her grandparents took her to see the musical Cats, but being from a rural town in southern Illinois, they didn’t have too many acting opportunities at first, as they were related to MTV. The actor started out in high school plays before managing to move beyond the stage to other local projects. In 2015 they really started their career with two short films. According to IMDb, in one titled Artificial Intelligence, Germaine plays a scientist in a story heavily inspired by the hit Valve game Portal. In her other early venture, Germaine had a role in the comedic five-minute short Latte Feelings, about an overtly positive coffee shop customer.
Unnoticed by the frequent customer, his thoughts are heard by everyone in the cafe. That’s not necessarily a bad thing for others, including Germaine’s barista character, though. The customer showers everyone with compliments, especially Germaine’s character, who is described as kind and hardworking. It would be a few more years before Germaine got a chance to star in her first major film. In 2019, the actor starred in the offbeat comedy Trinity Baby, about a dominatrix named Trinity who gains the ability to speak to the dead after inhaling an aerosol can. Germaine plays Baby, Trinity’s musical partner who must deal with Trinity’s newfound supernatural ability.
