Perhaps I'm overrating the film, but besides being engaged
by the dualities and parallels, I was very moved by the performances and very
impressed by how the director presented everything without sentimentality or
judgment.
The real Alice Liddell (1852-1934) really did marry
cricketer Reginald Hargreaves, really had three sons (two of whom died in WWI),
and really did visit Columbia in 1932 for Lewis Carroll's centennial.
The full nature of Liddell's relationship with Carroll
remains unconfirmed. The film implies he
was infatuated with her, probably but not definitely sexually. The scene in the darkroom, where they're
pulling the shade and shutting the door is the most suggestive. In real life she was a remarkably beautiful
girl whom Carroll drew or photographed hundreds of times.
