If you've seen Ninja Assassin, then you might recognize Mr. Thang right here; he played the younger version of Raizo (sans all that hair, of course), and you know him as "Honey Abs" from MBLAQ.
His face is angelically luminous, rivaling that of even his own mentor Rain. He displayed exceptional stamina and ability in Ninja Assassin (as he has in performance after performance after performance after performance with MBLAQ), and was willing to shave his head and learn a new language for his first major film role. That's a lot to ask of a 22-year-old (and at the time he was 21).
As stated in interview, he didn't get to participate in the Ninja Assassin press conference, for which he was kinda sad. And I'm kinda sad too, because it means less Joon footage.
Mr. Thang here is not an underappreciated musician, however, as you may have noticed (though I think "musician" is a bit too strong a term here), nevertheless I too hope he some day gets his chance to "take his top off" during a performance.
(You know...like this? Is this too much to ask for? 'Cause if it is you can tell me...not that it'll make any difference).
Anyhoo, I'm not sure what projects he's got coming up, but the little sis has made it clear that if MBLAQ goes on tour in the US, I'm taking her to see him (she calls him her "husband").
