I found an interesting article about Elizabeth from PR Inside, it says:
Newly married comedian Jimmy Fallow was saved from a life of celibacy by a childhood crush on actress Elizabeth Perkins.The star – who wed longterm partner Nancy Juvonen on Saturday (29Dec07) in the Caribbean, dreamed of becoming a Catholic priest until he watched Perkins in 1988 movie Big and fell in love with the opposite sex.
Fallon says, “Growing up, I wanted to be a priest. “I was an alter boy and I served Mass at 6.45 in the morning – I liked the smell of Catholic church in the morning. Then in seventh grade, I decided I did not want to give up sex because I got a huge crush on Elizabeth Perkins, who was starring with Tom Hanks in Big.”
