I would like to know the name of a movie and who starred in it, but only know the plot: a couple go on a safari for their honeymoon; they encounter a lion or tiger. as a result the wife stops aging (like Dorian Gray). She leaves her husband and daughter. Later in life she has a chance meeting with her family; her daughter now engaged. However, the daughter's fiance falls for the mother. This is all I remember.
