Looking for a male, improv comedy actor

I am creating a comedy, satirical short film video as a project for a client. The film focuses on a skinny individual who is attempting to "fit in" to future society as an overweight individual, by dressing, living and going out in a fat costume for 48 hours. This film is designed to be set in a dystopian future, but the film is also designed to be recorded and played as a YouTube-style film, not dissimilar to challenge videos currently found on the platform (I.e. designed to look self-shot and self-produced). Character needs to possess certain qualities, including clumsiness and being gassy. Ideal actor should be able to perform decent improvisation and have a comedy background.

Required: Creation of a realistic costume to simulate obesity, ability to meet character elements and exceed expectations, ability to act in private and public places, ability to create comedic content and strong plot-driven video

Video Length: 5-10 minutes
