Jake Gyllenhaal's cute . . . but apparently not nearly as irresistible as a talking bunny.

The weekend's clear box office winner was Hop, the Easter-themed animated flick starring James Marsden and featuring Russell Brand as the voice of the Easter Bunny's son, "E.B.." The family-friendly film exceeded industry expectations and earned an impressive $38 million in its debut weekend -- the biggest U.S. opening so far of 2011.

Source Code, the mind-bending thriller starring Gyllenhaal and Michelle Monaghan, wasn't even a close second, garnering $15 million in total box office receipts.

Just behind that was freaky, low-budget horror flick Insidious starring Rose Byrne and Patrick Wilson, nabbing $13.5 million for its first weekend out.

Last week's number 1 movie, the similarly kid-friendly Diary of a Wimpy Kid, landed in the fourth spot with another $10.2 million earned. Rounding out the top five? Newly single Bradley Cooper's Limitless, yielding $9.4 million in its third weekend in theaters.
