Amy Redford film
What Comes Around, Hardesty put in a performance that reviewer Marya Gates observed was so "dynamic" that it outshone the performance of the lead actress. Hardesty appeared as Brooke in the 2024 film ''
It's What's Inside, which was shown at the Sundance Film Festival and acquired by Netflix, but Rolling Stone'' reviewer David Fear noted that her character lacked sufficient development even when compared to the thin characterizations of the film's other roles. In 2025, Hardesty starred opposite
