When not directing – and sometimes while directing – Kelsea also acts! She can be seen in Jess Zeidman’s forthcoming feature film, Human Theories, which will premiere at the 2026 Tribeca film festival. Kelsea had a leading role in the feature film Vanilla, and the Hollywood Reporter said some pretty nice stuff about her performance. You can also see her being pushed into a car in Paula Gonzalez-Nasser’s 2025 Tribeca Film Festival breakout, The Scout. There are no small roles, just actors who look very small through a windshield.
