Clash of the Titans’ use of 3D may not have been favorably reviewed, but that didn’t keep the remake from conquering the box office.

The Warner Bros. film, which was delayed for a last-minute technology upgrade, officially became the biggest Easter weekend opener to date. Titans’ $61.2 million topped previous holiday champ Scary Movie 4 and bested 1999’s The Matrix to become the best April release ever. (That 1999 film debuted to $27.8 million.)

Why Did I Get Married Too?, the sequel to 2007’s Why Did I Get Married?, gave Tyler Perry his second biggest open to date. The movie, which falls behind 2009’s Madea Goes to Jail ($41 million), is actually Tyler’s best non-Madea entry.

Meanwhile, The Last Song, Miley Cyrus’ first major film sans secret identity Hannah Montana, unfolded to a $16 million debut ($25.4 million since Wednesday) and a fourth-place finish.
