Angela Cartwright and Veronica Cartwright through the years: From 'Sound of Music' to 'Alien' to today

Few child actors ever got to experience Hollywood quite like Veronica Cartwright and Angela Cartwright.

The English-born sisters grew up in Los Angeles, where they were welcomed into the Hollywood circuit at very young ages. Veronica's earliest roles were in episodes of "Leave it to Beaver" and "The Twilight Zone," and she was just barely a teen when she was cast in Hitchcock's "The Birds."

Meanwhile, younger sister Angela was acting professionally as well, landing her first role at just three years old. She spent an impressive seven seasons on the air in "The Danny Thomas Show" before snagging a spot as one of the Von Trapp children in "The Sound of Music."

As she hit her teenage years, Angela continued working steadily. She most famously played Penny Robinson on "Lost In Space." But after tying the knot in 1976, she mostly refocused her attention on her two children and her photography. She's now 65.

Veronica, for her part, continued to rack up more roles, appearing in countless TV shows and movies through the years. Seriously, her resume never ends! From '90s shows like "Baywatch" and "ER" to more recent shows like "7th Heaven" and "Revenge," this woman, now 68, is truly a Hollywood staple.

(Original Caption) Soda Break. Hollywood, California: Four talented young actresses (left to right) Debbie Maldow, Karen Balkin, Veronica Cartwright and Diane Mountford, take a refreshment break between scenes on a schoolroom set of The Children's Hour. Karen Balkin plays the role of Mary Tilford which is considered the best role written for a child and surely one of the most repellent. The film is being produced and directed by William Wyler.
