Arquette casts son in 'Medium'

Patricia Arquette has admitted that she cast her own son in an upcoming episode of Medium.

The actress, who plays Allison DuBois on the NBC drama, revealed that she was forced to ask Enzo for help after failing to find a suitable actor for the role.

"We were casting very quickly and we were shooting while we were casting, and the character is 40 years old and we needed him when he was like 16 or 18 years old," Contactmusic quotes her as saying.

"At that point your face is very formed so when we put them next to the father, they looked too big, or they didn't look like the man we'd cast [as the dad], so I called my son the night before and said, 'You have to do this'. He's 20 but he looks pretty young."

However, Arquette insisted that her son would not be following in the footsteps of his acting dynasty family, which includes uncle David and aunt Rosanna.

"He's not an actor. I went through his lines with him every night. He's going to art school, it's not a priority for him," she said.
