This isn't in the book and while the film has added things into the film which weren't in the books this would steer to much from canon so I doubt J.K Rowling would allow it. The picture is probably a fake.
Harry Potter and the Deathly Hallows is set in 1997. Lily (Evans) Potter died when she was 21 in 1981.
There may be auditions for: Rose Weasley Hugo Weasley James Potter Jr Albus Potter Lily Potter Jr Lily Evans (as child) Severus Snape Petunia Evans
Yes, he has been on Albus Dumbledore's side since 1980 when a threat was made on the life of Lily (Evans) Potter.
Yes, it will.
No, they do not appear in the movie.
No, I don't think so.
probably as that is one of the most important scenes
[spoilers] Harry survives the war and goes on to become an Auror and marry Ginny. They have three children: Lily Luna Potter, James Sirius Potter, and Albus Severus Potter (who is noted for being the only one of the three to inherit Lily Evans' eyes). He remains best friends with Ron and Hermione (who also marry, and have Hugo and Rose Weasley).
I don't think u would have to be a redhead to audtion for Lilly Evens because in the book it didn't say Lilly is a redhead.
Lily Evans, who later became Lily Potter.
They are named after James Potter, Sirius Black; Albus Dumbledore, Severus Snape; Lily Evans and Luna Lovegood.
Possibly. The general public have never been told if they will be in it or not. They may appear in trailers but it is unlikely, most likely we will have to wait until part two of the film comes out next year.
