Ugh, I'm still waiting for the day I can find raws for "Love or Not"! Really hoping I can subs and raws for "Seven Prisoners" and "Frankenstein's Love".
Also: Miyavi (as a late edition it hadn't been announced when I wrote this) has lended his acting chops in "Kong'}", with Kamui Gackt providing voice acting as well!

I'm not an expert on idols of course either, but being trained in acting depends on the company. Many Korean companies are pushing acting more recently well as singing/performance. I'm not so well versed at which companies and idols however.
A lot of bigger Japanese companies such as Johnny's, LDH, and AKB groups invest more in acting as well as music and performance since their label of 'idol' does usually encompass singing/acting/as well as other talents. So while idols should be 'trained' in acting, this does not mean that they were trained as strongly, or for as long as they were in singing/performance. In my opinion, you can really see it in AKB where all of them are trained as actresses, but only a few of them really excel at doing so in comparison to the whole group.
I guess what I'm getting at is that most idols are trained in acting, but not all the companies emphasize acting as much as musical talents despite Japan being more 'idol-actor' friendly.

I enjoyed 'Attack on the Pin-Up Boys' for what it was. Just looking at it a touch harder, it really wasn't up to snuff with my usual tastes.
"Innocent Lilies" is worth a watch if you don't mind cringing a bit. It's worth a shot, but it's no offense taken if it's not your cup of tea.
And Takuya has a few other roles in 'Ai Ore!' and another Japanese movie that recently came out. Japan loves him as an actor, so I recommend his movies/dramas a lot!
100% accurate that I didn't know that Park Hyun Shik is an idol as well. (I haven't followed ZE:A closely, or see his dramas. Thanks for pointing it out!

I've been really excited for his roles as well! I've been looking forward to "My Korean Teacher" for months!
