Duncan and Lilly Kane (Teddy Dunn and Amanda Seyfried)
Everyone basically knows what Amanda Seyfried (Lilly Kane) has been up to — star of HBO’s Big Love (a Veronica Mars cast reunion show, basically), scream queen (co-starring with Veronica alum Kyle Gallner in Jennifer's Body), romcom extraordinaire (Dear John, Letters to Juliet, and Mamma Mia!), and Les Misérables scene-stealer — but the same doesn't go for her on-screen bro.
Teddy Dunn (Duncan Kane) has only made three movies since Veronica Mars ended: Jumper (with Hayden Christensen and Rachel Bilson), Kill Theory, and A Good Funeral. No word on if he’ll turn up in the movie, but we have our doubts.
