Can anyone identify this biplane from a TV show?
My vote would be a Waco UPF-7 without the engine cowl:

Looks like the one in the OP post has a different engine in it or at least a relocated cooler, but the struts and windscreen design look very similar. (Struts on the right side are distorted by perspective, look at the ones on the left). Gear bracing is also pretty close.
