Angelina Jolie with Jon Voight in Lookin' to Get Out (1982)
Their relationship may be famously strained now, but once upon a time a 6-year-old Jolie played daughter to dad Voight in his film Lookin' to Get Out. That was obviously the debut of one of the biggest stars of our time. Only time will tell if her own children will continue the trend with their upcoming appearance in mom's Maleficent.

Shiloh Jolie-Pitt with Brad Pitt in The Curious Case of Benjamin Button (2008)
A split-second appearance was all we got of baby Shiloh in her dad's Oscar-nominated movie. Of course, thinking about a dad who was aging in reverse holding his own spawn is enough to make your head hurt.

Jaden Smith with Will Smith in The Pursuit of Happyness (2006)
Jaden went on to star in his own film (2010's The Karate Kid) but before that, audiences got to see if Smith's son had some of Dad's box office magic. It turned out, he did. Whether the 8-year-old was crying into his dad's shoulder or showing steely resolve, moviegoers were eager to line up for the next generation of Smith.

Willow Smith with Will Smith in I Am Legend (2007)
Before she was whipping her hair (back and forth) Willow was winding her way into our hearts with her small role in Dad's action film, I Am Legend. Up next, she'll break away from Will and reportedly star in a remake of Annie. Children of superstars — it's a hard-knock life.

Tatum O'Neal with Ryan O'Neal in Paper Moon (1973)
They may now famously put the ''dys'' in dysfunctional with competing Oprah show appearances, but at one point O'Neal was an Oscar-winning child actress who costarred alongside dad as a father-daughter team in this crime drama.

Rumer Willis with Demi Moore in Now and Then (1995) (also Striptease, 1996, and Bandits, 2001)
All three of Bruce Willis and Demi Moore's daughters have costarred with their famous parents. First up was big sister Rumer, then 7, as Moore's young daughter in the classic coming-of-age film Now and Then, and later, perhaps a little creepily, as the daughter of her stripper mom (Demi Moore) in Striptease.

Scout and Tallulah Willis with Bruce Willis in Bandits (2001)
Middle daughter Scout, then 10, and sister Tallulah, 7, costarred alongside dad in Willis' crime comedy that also featured Billy Bob Thornton and Cate Blanchett. Both girls also showed up in mom Demi Moore's The Scarlet Letter (1995) as an infant Pearl and young Pearl, but with the dubious history of that film, maybe it's best forgotten.

Tallulah Willis and Bruce Willis in The Whole Ten Yards (2004)
The youngest of Bruce and Demi's children got back in on the fun in dad's sequel to the comedy The Whole Nine Yards when she was 10.

Maude and Iris Apatow with Judd Apatow and Leslie Mann in Knocked Up, 2009 (also Funny People, 2009, and This is 40, 2012)
Apatow movies are easy to get confused with home movies: Apatow's real-life wife Leslie Mann often stars alongside their two children, daughters Maude and Iris, in the director's films. The kids made their debut in the comedy Knocked Up, with Paul Rudd playing their father. The two girls will reprise the roles in December release This is 40.

Ella Travolta and John Travolta in Old Dogs (2009)
The movie may have explored the familiar adage about old dogs and new tricks, but it was clear that one thing that hadn't changed was Travolta's love for his then-8-year-old, who appeared in the film to yuk it up with her dad in this family comedy.

Lucie Arnaz and Desi Arnaz Jr with Lucille Ball in The Lucy Show
Desi Arnaz Jr was born the same day as Lucille Ball's fictional son on I Love Lucy, Little Ricky. He never played Ricky but he did have an uncredited role as an extra on the show, as did his real-life sister Lucie. It would be a few years before the siblings would appear onscreen with their famous mom again, first on The Lucy Show and later on Here's Lucy.

Lorraine Nicholson with Jack Nicholson in Something's Gotta Give (2003)
Her bigger supporting turn in Soul Surfer was eight years away but the then 13-year-old was happy to take her place in her father's hit movie, even if it was as more of an extra credited as ''girl in the market.''
13 of 15
Sean Astin with Patty Duke in Please Don't Hit Me, Mom (TV movie) (1981)
Taking their real-life mother-son dynamic to disturbing extremes in this television movie, a 10-year-old Astin played an abused son to mom Patty's abuser role in his first acting job. But Astin soon went on to star, sans mom, in '80s classics such as The Goonies and Rudy.

Judy Garland with Liza Minnelli in In the Good Old Summertime (1949)
Both icons in their own right, a 3-year-old Minnelli (seen here on set with Garland and Van Johnson) appeared with her famous mom in this romantic comedy. Showing up just in the last scene of the film, the performance kicked off her own long showbiz career. Minnelli is one of just a few performers to have won an Oscar, Grammy, Emmy, and Tony.

Eva Amurri with Susan Sarandon in The Banger Sisters (2002)
The famous mom and daughter duo play guess what... a mom and daughter duo in this comedy (costarring Goldie Hawn) about two former rock groupies who are now all grown up. But it was not the first time the then-17-year-old and her mother appeared together: Prior, Amurri cameoed as a school child in mom's drama Stepmom (1998), and the two also costarred on an episode of Friends together in 2001.
