I'm just another RPH and I really like Amanda Seyfried. I'm just here to help.
I have a lot, anon. A lot.
How about: Britt Robertson, Ashley Benson, Katelyn Tarver, Blake Lively, Taylor Momsen, Taylor Swift, Sasha Pieterse, Emma Stone (sometimes), Leven Rambin, Jennifer Lawrence (sometimes), Imogen Poots, Freya Mavor, Emma Roberts, AnnaSophia Robb, Heather Morris, Claire Holt, Dianna Agron, Emily Browning (sometimes), Emily Osment, Candice Accola?
I’m thinking Logan Lerman, Emily Browning, Justin Kelly, Saoirse Ronan, Joe Cole, Dave Franco, Colin Ford, Jackie Emerson, Katelyn Tarver, and Britt Robertson would work nicely for a role like that. However, almost any young actor would be fine.
I think Dianna Agron, Clemence Poesy, Karen Gillan, Emily Browning, Amanda Seyfried, Shelley Hennig, Lea Michele and Lily Collins could work very well for a role like that. Shelley, Clemence, and Lily are rarely seen in that role, but Dianna, Karen, Emily, Lea and Amanda more commonly are.
Hm, well, he’s twenty-seven, right? He looks to be in his mid-twenties as well, so I’d say twenty-four could be the youngest, maybe twenty-three. As long as you don’t make him a high schooler, I think you’ll be alright.
