It's an age-old battle: the battle of the sexes, and it's played out onscreen in "Think Like a Man," opening nationwide Friday.

Based on Steve Harvey's bestselling book that outlines rules for ladies for the dating game, "Think Like a Man" provides context for Harvey's rules and tackles common dating problems such as the "momma's boy," the guy who won't commit, and the player.

"If I learned something from the book and the movie, it's to put emotions to the side," La La Anthony, who plays Meghan Good's best friend in the film, told ABC News Radio. Anthony is just one part of an ensemble cast that includes Oscar-nominated actress Taraji P. Henson, who plays a successful career-driven women who doesn't buy into Harvey's dating rules, and comedian Kevin Hart, who portrays a not-so happily-divorced single guy.

Also starring are Terrence J, who plays a "momma's boy" who has to choose between the women in his life. "Entourage's" Jerry Ferrera is the non-commital boyfriend to Gabrielle Union's character, while Michael Ealy plays a broke "dreamer" who attempts to woo Henson's high-powered character.

As the women begin to follow Harvey's rules, including making their partners wait 90 days before sexual intimacy, it makes you wonder if the "Family Feud" host is onto something.

"All the women in this [film]…and their approach to [dating] were smart, and it forced men to look at them and say, 'Wow, I have to take her seriously,'" Hart, a real-life divorcee, told ABC News Radio.

Still, it's not just women who have taken Harvey's rules to heart. Much like the movie where the men later use Harvey's dating rules against women, star Romany Malco also believes in waiting to have sex with a potential partner.

"I'm the kind of guy who does like to abstain," Malco admitted. "I don't necessarily want to jump in bed with someone that I'm not familiar with. I do believe in taking time."
