Jim Carrey's "Yes Man" beat Will Smith's "Seven Pounds" at the North American box office Friday with $6.4 million in ticket sales. That's an unusually low performance for a Carrey comedy.

Meanwhile, "Pounds" debuted at No. 2 with only $5.2 million, a rather disappointing result for Smith, whose films usually picked up a lot more on opening day. Following in third place was new entry "The Tale of Despereaux," which collected $3.5 million.

Down to No. 4, last week's winner "The Day the Earth Stood Still" earned $2.8 million, lifting its domestic gross to $41.3 million after a strong one-week run. Seth Gordon's holiday comedy "Four Christmases" followed at No. 5 with $2.2 million, reaching a total haul of $94.6 million.

Other results: "Twilight" ranked sixth with a daily gross of $1.6 million; "Bolt" pulled in $1 million; "Slumdog Millionaire" took home $755,000 from only 589 locations; and "Australia" finished with $625,000.
