Margaret: David: 51-year-old Dan Foreman, (Dennis Quaid), is the head of advertising sales at the magazine, Sports America, a job he's held successfully for several years.
Dan is married to Ann, Marg Helgenberger, who has just discovered that, at the age of 40, she's pregnant again they already have two teenage daughters.

On his left is a razor-stubbled veteran, a quarter-century older, wearing jeans and a leather jacket and joking with those same reporters, carefully steering them back on course when they dare to venture off message.
The message is Universal Pictures’ upcoming film, “In Good Company,” starring Topher Grace and Dennis Quaid.
His 7 month old marriage is coming to an end, and he's basically lonely.
Rather unwillingly, Dan invites him home for dinner and thats where Carter gets to know Dan's elder daughter, Alex, (Scarlett Johansson).
“Having to act opposite someone who is so good, for three months, was daunting,” Grace says. But Dennis, from the first day, was the nicest, most easygoing guy.” He blushes beet red then adds, “Well, come on, it’s hard for me to say in front of him, but it’s just fame, that his talent has bought him, that’s intimidating.” Famous, Quaid definitely is.
After dropping out of the University of Houston, he appeared in a handful of films and television movies then landed a lead in the 1979 runaway hit, “Breaking Away” followed by “The Night the Lights Went Out in Georgia,” for which he wrote some of the music. Unfortunately, so did the booze and drugs, which reached a visible crescendo in 1989 when Quaid played the late Jerry Lee Lewis in “Great Balls of Fire.” Quaid’s first marriage, to actress P. Soles, had ended in 1983 after five years, and he became engaged to actress Meg Ryan.Could it be any worse, well it could when Dan discovers that the recently divorced Carter is now dating Alex making things extremely awkward for all involved.So as already mentioned "In Good Company" is not what you would necessary expect from a movie which is a drama, a comedy and a romance.Dan Foreman (Dennis Quaid - The Day After Tomorrow) may get up before the crack of dawn for his job in advertising but he loves it nearly as much as he loves his wife and daughters.But his life is going to be shaken up when the sports magazine he works for is taken over by a huge conglomerate and in the shake up he is demoted from head of advertising to have Carter Duryea (Topher Grace - Mona Lisa Smile) brought in as his boss, a man half his age and with no real experience.But "In Good Company" isn't what you expect, this isn't some movie full of set piece comedy where by the end of the movie every one is living happily ever after, instead it is a movie about how funny life is, how awkward moments may break the tension and how things don't always end perfectly despite Hollywood liking us to believe otherwise.
