Writer/director Judd Apatow (The 40-Year-Old Virgin) returns with an affectionate comedy about a one-night stand with unexpected consequences. Katherine Heigl (Grey's Anatomy) joins Virgin alums Seth Rogen, Paul Rudd and Leslie Mann for comic look about the best thing that will ever ruin your best-laid plans: parenthood. Allison Scott (Heigl) is an up-and-coming entertainment journalist whose 24-year-old life is on the fast track. But it gets seriously derailed when a drunken one-nighter with slacker Ben Stone (Rogen) results in an unwanted pregnancy. Faced with the prospect of going it alone or getting to know the baby's father, Allison decides to give the lovable doofus a chance.
