In 2021, Greg Sestero has admitted that there were no plans for Big Shark to begin production and that the "trailer" released online in 2019 was nothing more than a concept pitch, but he has expressed interest in seeing the film get made in the hands of another filmmaker. In March of 2023, a new trailer unexpectedly dropped, revealing that Wiseau had finally completed the film and would be released later in the year.
Tommy Wiseau constantly changes gloves in the film, ranging from red, blue, yellow and black gloves through the film. Only a handful of scenes have him without gloves.
