“Katy Perry: Part of Me” attracted enough paying customers in its opening weekend to make the top 10, but missed crossing a threshold that makes concert-based biographies a viable genre.

Opening the day after a national holiday, Paramount’s 3D Perry film grossed an estimated $10.2 million over four days on 2,730 screens, the studio estimated. Its weekend gross was $7.1 million.

Those numbers pale in comparison to Paramount release last year of “Justin Bieber: Never Say Never,” which pulled in $29.5 million the weekend before Valentine’s Day. It would go on to make $73 million, making it the top film in the genre, according to data collected by BoxOfficeMojo.com.

“Hannah Montana/Miley Cyrus: Best of Both Worlds” is the biggest opener among all concert films, grossing $31 million on a mere 683 screens in February 2008. “Michael Jackson’s This is It,” with a $23.2 million opening, and “The Jonas Brothers 3D Concert Experience” ($12.5 million) also bested Perry’s opening tally. The Jackson and Jonas films, however, opened on more than 3,000 screens each.

Most of these films have a shelf life of about five weeks and – at best – drop about 50% each successive week at the box office. The Perry film will likely end up in the $16 million to $19 million range, placing it between “Madonna: Truth or Dare” at $15 million and the $19.2 million the Jonas Brothers film eventually grossed.
