The Big Bang Theory executive producer Bill Prady confirmed the news to the site, and also revealed that Wil Wheaton's appearance would likely be during the November sweeps month. Here's an excerpt from the site which describes how the continued rivalry between Jim Parsons' Sheldon Cooper and Wheaton will ensue:
"We started talking about the idea of minor celebrities cutting in line," Prady says, "and we thought it might be funny to have our [Big Bang] guys waiting in line for a one-time-only midnight screening of something like Raiders Of The Lost Ark with restored footage, and Wil Wheaton and his three friends cut the line. When it comes time for our guys to get in, the line stops; Wil took the last four seats and Sheldon is just furious. Because it doesn't make sense to him. Wil's celebrity is not applicable here. This is not Star Trek. It's just wrong."
