Jamie Bell (Tintin; some other period drama but I'm not sure which. What do you think?)
For Mary Crawford:
Eliza Bennet (she looks kind of older than she is in this picture, she's 21. Probably younger than Kimberly Nixon, but I don't think it matters.)
For Henry Crawford:
Simon Woods (Cranford, Fake P&P)
For the young Bertram kids.....ummm
Asa Butterfield (Boy in the Striped Pyjamas; Age 16)
Any ideas for the young Tom Bertram?
The young Maria and Julia: I have no idea!! Help Me!
