[Update]  -- His agency J.Tune Camp rep responded to the reports as they told Sports Seoul on the 22nd, "[Lee Joon] has received the casting offer and is in talks but nothing has been confirmed yet... Lee Joon is not conducting individual activities at the moment as he is putting all his strength into the preparations for MBLAQ's new album set for release this March."

So it seems we'll have to wait a bit to see if they'll confirm the casting or turn it down! Cross your fingers!
