DVD Tuesday: ‘Knocked Up’, ‘Shut Up and Sing’

One of 2007’s most popular comedies arrives on DVD this week, starring Seth Rogen and Katherine Heigl as a mismatched couple preparing for a baby after a drunken one-night stand. The film was written, directed and produced by long-time TV and film producer Judd Apatow, who also wrote The 40 Year Old Virgin, and his results with Knocked Up offer the same mixed comic and light-dramatic style.
