I saw a bit of this on TV recently and was intrigued enough to look it up to see if I wanted to catch all of it later. Briefly this is a 1948 time travel love story...

Jennie Appleton (Jennifer Jones) is a mysterious young woman who enters the life of starving artist Eben Adams (Joseph Cotten). Jennie claims to be the daughter of highwire performers who are currently performing at the Hammerstein Victoria Theater, except that the theater was demolished years ago. When Eben first meets Jennie, she is schoolgirl-aged. Over the next several months, she grows up before his eyes. Because Jennie has become his muse and he is falling in love with her, Eben seeks to unravel her past. (taken from IMDB)...anyone seen this?
