MBLAQ's Lee Joon shows us his body yet again for his upcoming movie "An Actor is An Actor".

In an interview at the Busan International Film Festival, Lee Joon talks about his new movie, his adlibs, and the bed scene that made him expose his body for 24 hours.

The idol-actor said, "I put in a bit of ad-lib in my parts for the movie. I didn't add them during parts with a lot of dialogue, but during the bed scene, I said the line, 'If you're sorry, do it with me.'"

According to the director of the movie, they let Lee Joon do his ad-lib during the filming because he seemed pleased about the line, but he plans on cutting the dialogue during the editing process.

Meanwhile, at the same interview, Lee Joon expressed that he has never received praise for being a singer, but is being complimented for his acting.

"I'm a member of MBLAQ, but I never get complimented on my singing, and sometimes I get cursed at because of it. I practice my singing a lot but I never get praised. On the other hand, people notice my acting more often. My first movie was in 2009 and I have improved since. I look forward to the audience's reaction."

Look forward to Lee Joon's acting in "An Actor Is An Actor" which premieres on October 24.
