The Selling's cast is largely unknown (unless you're a Sketchfest diehard), but it does feature a cameo by Rocky Horror Picture Show (1975) royalty Barry Bostwick, playing a daffy exorcist. "We were fans of his, and we approached his agent. Barry read the script, and he really liked it and wanted to do it," Lou says. "It just kind of went from there, and he worked for less than he normally works for — he's also a fan of classic horror. He was amazing to work with, just a great guy."
