Slave2Moonlight, I think Jessica Biel might make a good Meg, thats just off the top of my head though. I may have said this in here, but Rachel Weisz might make a good Jane?
Some very interesting suggestions here. In regard to my artwork and personal preferences, I will likely use Reese Witherspoon (based more on her pre-Legally Blonde work, when her face was a bit fuller and cutesier, and more my type (like in Cruel Intentions, Pleasantville, and stuff like that) as Katrina Van Tassel. I think Jennifer Love Hewitt will likely be my Megara. I chose Rachael Leigh Cook for Belle. Perhaps there are better choices out there if trying to get as close a physical likeness to the toon as possible, but I still think she's perfect for the part. Someone I used to like as a physical match to Belle was the girl from "My Boyfriend's Back" and "Fright Night part 2," though I doubt anyone remembers her and I forget her name at the moment. Her voice wouldn't have been very good for it though. As for Sandra Bullock, I have never found her attractive. Always felt she was too masculine looking. Jessica Biel has had her moments and has an amazing physique, but I've never been wowed by her face very much. I don't know who I'll use as Esmerelda yet. I am not beyond considering the voice actresses, of course (used Pocahontas's, after all, though I have been reminded of a couple of actresses recently I might have liked in the role as well), and the ages are not too important, but I'd like to use current stars as often as possible. If someone is too old for a role now, I might use reference material from when they were younger, or just make adjustments as I draw, as with Elisabeth Harnois as Alice and Kay Panabaker as Wendy in my art piece.
Well, again, the age isn't important for the art piece I'm doing. I can always use younger photos for reference or just make my own adjustments. Some of the girls I used are too old for the roles, but they were once perfect, and that's why I used them.
I'm not much of a Demi Moore fan myself, but I'm not huge on Esmerelda either. I'll check out some pics of her in her younger days and consider her for the part. She definitely is the person who always comes to my mind. However, there are probably a lot of potential Esmereldas out there right now, I just haven't been looking for her yet. Demi will probably be my first consideration though.
