I'd be interested in playing the father. I'm not sure how much you already have in mind about the father, but here are my ideas:
Name: Carl (Same last name as the daughter, of course)
Age: late 40s
Occupation: IT manager at a corporation
Actor: Alan Rickman
Personality: Very nice in public, Carl makes up for it at home. It's not that he's nasty so much as it is that he's... used to having his way at home. He's brought up <daughter> with a firm hand, but while he's been strict with her in the past, he's never been abusive, and what she remembers of his treatment of her mother wasn't either. Of late, however, he's been noticing his daughter's newly-adult body... and indeed, part of how he came to be attracted to her friend was in sneaking peeks at the two of them as they'd use the pool, etc.
Ons and Offs: See my ons and offs post
If you do have any firm ideas about the father that any of this doesn't match up with, let me know and we can see if we can work it out. Thanks!
