@@SaraHessXXIV Firenzi is not only one of the actors in the movie, he is the movie's editor and co-writer (much like in VGHS), and the movie itself is created in large part by 5secondfilms, a short-form sketch group that is still active here on RU-vid. I believe 5secondfilms is founded by Firenzi. If you are familiar with 5secondfilms, you will find that multiple members of the group play roles in VGHS, such as those of Jumpin' Jax and Alliterator.
While not a big movie, Brian Firenzi was hilarious in Dude Bro Party Massacre 3. The name sounds stupid but it's genuinely one of the funniest movies I've ever seen
