Justin Long and his 'horrifying' 'porn star' mustache get laughs on TODAY

Justin Long ostensibly came on TODAY Tuesday to discuss his new indie movie, "A Case of You." But the real discussion took a hair-pin turn, as the anchors and Long focused on his "porn star" mustache.

"I'd like to say, 'You're welcome, America,'" said Long, who stars in and co-wrote "Case," as he stroked his facial hair. "It's horrifying. I'm sorry. Most everyone in my life is very much against it, but it's for a job." 

But, he assured the audience, "I'm not playing a '70s porn star."

Willie Geist noted, "I'm a huge fan of the other Justin Long, but I think you do some good work too."

Turning to the camera, Long noted, "Willie's alluding to, in case you don't know, if you're living under a rock, that there's a porn star named Justin Long. ... His friends call me the 'poor man's' him."

Fortunately, there was something else worth talking about, too — the movie. In it, Long's writer character romances Evan Rachel Wood's barista character by constructing a persona online that he thinks will impress her — and then has a hard time living up to it. "This guy takes it a little bit too far, and is very disingenuous," said Long, then added one more reason to see it: "I'm not wearing this," he said, touching the 'stache. "This does not make an appearance."

But heads up, "Game of Thrones" fans: Peter Dinklage does make an appearance in the film. 

"A Case of You" is out on iTunes, on Video on Demand and in theaters on Nov. 6.
