One of her most vivid memories of filming "It's a Wonderful Life" was the large Christmas tree in the Bailey house. Grimes' own family had a two-foot-tall tree that stood on a table. She enjoyed the snow on the set, even thought it was artificial, because she had never seen real snow.
She rang the Closing Bell on Wall Street in 2003.
She still has an angel ornament from the Christmas tree in the movie It's a Wonderful Life (1946).
