Who Was in That Thing is a 2012 documentary film by Ian Roumain and Michael Schwartz that features sixteen male character actors discussing their careers as working actors below the film star level but who are often recognized as being "that guy" who was in "that thing".{{cite web|author=Ryan Messer|title=Cinemavore: 'That Guy ...

The film was produced by Roumain, Schwartz and Brian Volk-Weiss for New Wave Entertainment. Doug Shanaberger described it as a "wonderful new documentary", saying: "If you're wondering who they are, that's half the point. But you'll recognize them, and that's the other half."{{cite web | url = http://www.observer-reporter.com/or/shanaberger11/10-24-2012-OR-Columns-Shanaberger | title = 'Producers' regaining popularity with two area productions | accessdate = 2012-10-28 | last = Shanaberger | first = Doug | date = 24 October 2012 | work = Observer Reporter | archive-date = 2013-01-30 | archive-url = https://archive.today/20130130161315/http://www.observer-reporter.com/or/shanaberger11/10-24-2012-OR-Columns-Shanaberger | url-status = live }}
