As it turns out, Harold & Kumar Go to Amsterdam doesn't exist and that third Vegas film is just an overblown rumor.

When we sat down with Kal Penn on November 16th, we asked him about Harold & Kumar Go to Amsterdam.

"It's not called Harold and Kumar go to Amsterdam. Don't listen to imdb! IMDb is a pack of lies," Penn told /Film. "We don't know what it's called, it's untitled right now but it's not going to be called Harold and Kumar go to Amsterdam. We're shooting it in Shreveport, Louisiana starting in the middle of January."

When we grilled Penn for more details, asking him if the adventure stays in America, he claimed he didn't know.

"I just read the first draft and they're updating it... re writing it. So I don't know what the end result is going to be of the journey. But I laughed out loud when I read it. It's ten times funnier than the first one. I'm very very excited to go back to playing Kumar."

And what about the rumors of a third film in development called Harold and Kumar go to Las Vegas?

"It's hard to explain, and people misinterpret this. We're signed to a three picture deal, but that doesn't mean that we're going to make three movies. It just means that the producers have the right to force us to do three movies," Penn jokes. "It wouldn't be much of a force, John Cho and I are big fans, we enjoyed it so much and we want to do the sequels. But that's all it means."

The original Harold and Kumar Go to White Castle earned $18.2 million domestically, which while not considered a failure (as the budget was only $9 million), it was considered a disappointment.

"According to models that studios use, a movie like that isn't supposed to do well. And it didn't do well in the theaters," Penn admitted.

But the film finally found an audience on DVD, prompting the sequel. But the sequel might be the end for Harold and Kumar if they can't produce big numbers at the box office this time around.

"I think word gets out that someone signed a three picture deal and people assume that there are automatically going to be three of those movies, and their aren't," Penn told /Film. "It really depends on the success of the sequel in the box office, and not necessarily on DVD."

Penn also confirmed that negotiations were underway to bring Neil Patrick Harris back for the sequel. 

Clarification: We did some research and the first reference to a Las Vegas sequel was actually made by Penn himself in an interview with MTV in late 2005:

"I heard they were thinking about Vegas. John [Cho] and I are both, obviously, committed to doing at least two more, but whether or not they happen is not up to us," Penn told MTV.

It's funny how one comment in an interview eventually becomes fact on the internet.
