DREW BARRYMORE is so fascinated by her grandfather's acting legacy that she's making a documentary about it. The 26-year-old ET star admits she's determined to find out as much as she can about her ancestors, particularly grandpa JOHN BARRYMORE.

She says, "I've felt jealous of the people who've met members of my family I've never met. I've been at restaurants where someone will come up and tell me they knew my grandfather John. " She continues,

"You could never get me more all ears. The thing I really enjoy doing is watching their movies. Reading books they actually wrote and learning who really knew them. A lot of people get to spend their lives with their families. Since I didn't I at least feel lucky that my family left me all this documentation of their lives. " (MB/ML/KW)
