Haha, man that's a riot. I hope he does more as well, I mean it's a shame Roberta only gets one panel (want to see what the actress is like in "real life!") and Eda and Jane aren't even there at all.
Of course, this also means that unless Garcia's "actor" is just a really young looking guy, they had a 13 year old kid making out with a 20-something woman on camera
I kinda wish more mangaka would do stuff like this, "behind the scenes" footage of their cast and whatnot, just for fun.
