"My hat's off to the Roberts way. I find it much less duplicitous," he said. "A lot of what Angelina's doing is by design. She's a master at playing the press, playing Brad [Pitt], the kids, her directors, the movies. She's interested in being a walking headline. She's a woman filled to the brim with guile, and I think Roberts just wants to be her own gal."
In addition, exposure does not necessarily translate into box-office success, Bragman points out.
"Nobody gets more press than Angelina Jolie," said the author of the bestselling book, "Where's My Fifteen Minutes." "How did 'Changeling'open? Nine-point-four million. It doesn't go hand in hand."
Meanwhile, Roberts, Berry and Kidman have less to prove, according to Jacobs.
"Halle, Nicole and Julia have all been to the top, they've won best actress. If that's what it's about, they've already achieved it. They've been movie stars," Jacobs said. "They also had babies toward the end of their 30s or early 40s, which, for any woman, is a time of re-evaluation. As a woman approaches 40, there are also fewer roles. That's always been an unfortunate reality in Hollywood. So they have the pull to their families and fewer interesting roles."
Casablanca believes the lack of good roles for older Hollywood moms is often a bigger problem than finding a work-family balance.
"The whole discussion gets couched in 'they are raising a family now.' That becomes the story rather than the real story of how horrible it is for women aging in Hollywood," he said. "This is a town that does not allow women to age gracefully. [Meryl] Streep is the exception."
But Streep and Roberts are also two very different actresses. Roberts was one of the first female blockbuster stars, earning up to $20 million per flick and paving the way for someone like Jolie. Many will be watching to see what's in store next for the 41-year-old actress's career.
Other than collecting the occasional "paycheck" for movies like "Duplicity," Casablanca said he believes Roberts can afford to take her time.
"I think she's still putting together what kind of career she wants to have with her life [as a mother]," he said. "There's such frenzy from women who think they have only so many minutes [of their career] left. I do see Roberts fighting that more than someone like Nicole Kidman. More women should be like her."
