IGN report that Thomas Ian Nicholas, who starred as Kevin Myers in the first three American Pie films, has been tweeting a couple of photos from the set of American Reunion, which is due out in April next year.

Casting news has been coming over the past couple of months letting us know who’ll be returning, and one of Nicholas’ uploaded photos throws one more name into the ring: John Cho.

Cho had a small part in the first film as a drunk guy staring at a photo of Stifler’s mum (Jennifer Coolidge) and calling her a MILF, and he returned for the second and third films, and thanks to Nicholas’ photo, it looks like he’s going to be coming back for the Reunion.

Joining Cho will of course be pretty much all of the original cast reprising their roles, thankfully including some of the characters who didn’t make it into American Wedding. Alyson Hannigan and Jason Biggs will be coming back as the married couple, with a child, no less. Nicholas, Chris Klein, and Eddie Kaye Thomas will be back as Biggs’ high-school friends. Mena Suvari, Tara Reid, and Shannon Elizabeth will also be coming back, along with, of course, Seann William Scott, Eugene Levy, and Jennifer Coolidge. Two new names who’ll be starring in the fourth film are Dania Ramirez (TV’s Heroes and Entourage) and Katrina Bowden (TV’s 30 Rock), who will be playing Klein’s girlfriend.

The first photo shows Nicholas with Cho, with Cho sporting a bit of an uncharacteristic moustache, and Nicholas with a simultaneously crazy and excellent goatee. And the second photo shows the four boys, Biggs, Klein, Thomas, and Nicholas, reunited and hanging out for the first time in ten years (Klein didn’t appear in the third film). Excellent stuff. Without further ado, here are the photos. As usual, click to enlarge.
