Ryan Reynolds is coming out in another film where he plays a responsible father and husband. After the refreshing “Definitely, Maybe,” he now stars in “Chaos Theory,” a lesser, but still sweet romantic comedy.

The similarities between the two films however are many. Each film features a flashback to a younger Reynolds, and each film centers around a question of parenthood. In “Chaos Theory,” Reynolds’ over-protective dad tells his future son-in-law about the ups and downs of his own marriage to Emily Mortimer. He’s very funny as an uptight “time management” author who finally gives in to the random, chaotic nature of fate.

I like both of these films and find Reynolds an appealing romantic hero. He’s not coasting on his “sexiest man” moniker and after “The Nines” he has shown that he has range as a dramatic actor as well.

Next up for Reynolds is a comedy “Adventureland” and a drama with Julia Roberts called “Fireflies In The Garden,” both due out later this year.
