'Glee' Star Chris Colfer's Mini-Me Casting Was Spot-On

13-year-old actor Adam Kolkin had the show's casting directors saying 'Oh my god' at his close resemblance to Colfer.

A grilled cheese Jesus (or rather, Grilled Cheesus) wasn't the only visual worthy of a double-take on last night's episode of "Glee." The Fox series' casting directors should give themselves a big pat on the back for finding a nearly identical-looking actor to portray Chris Colfer's character, Kurt Hummel, at the age of 8.

In a series of flashbacks set to Colfer's melancholy rendition of the Beatles' "I Want to Hold Your Hand," Kurt recalls the days of his childhood following his mother's death. We see mini-Kurt walking through a cemetery hand-in-hand with dad Burt (Mike O'Malley) and later enjoying a lighthearted tea party.

The actor cast as young Kurt is 13-year-old Adam Kolkin. A high school freshman at Los Alamitos High School, Kolkin is a relative unknown who began acting at the age of 9 and has appeared in numerous television commercials for Disney, Advil and LG phones. His most notable film credit is the 2009 indie "Still the Drums."

Kolkin spoke with his local newspaper, The Orange County Register, about landing the plum part and recalled just how surprised casting directors were with his uncanny resemblance to Colfer.

"They all kept saying, 'Oh my god, oh my god,' " Kolkin said. After leaving the audition, Kolkin was quickly called back to sing a song. "I had prepared 'Walking on Sunshine,' " he said. "They were really surprised."

Kolkin spent a day on set filming his scenes, and although Colfer was not scheduled to shoot that day, he stopped by to meet his mini-me. "It was so cool," Kolkin said. "[The cast] were really nice."

Another happy parallel with his "Glee" character? Kolkin is also a member of his high school's show choir. "I had heard the show choir was really good, and I was interested in auditioning," he said. "I wasn't in [the show choir] Xtreme when I did the show but I am now."

There may be more flashbacks to come for "Glee." EW.com reported that casting calls have gone out for younger versions of Puck, Santana, Rachel, Brittany and Mercedes for the season's seventh episode.
