LOS ANGELES/NEW YORK - Transformers: Age of Extinction collected US$36.4 million in ticket sales over the three-day July 4 weekend, storming ahead of new films Tammy, Deliver Us From Evil and Earth to Echo to lead the U.S. and Canadian box office for a second consecutive weekend.

The special effects-laden blockbuster, starring Mark Wahlberg and a cast of form-changing robots, had the year's biggest opening weekend a week ago with $100 million in sales.

The comedy Tammy, starring Melissa McCarthy as a fast food worker who has a very bad day, was second with $21.2 million, according to studio estimates. Horror film Deliver Us from Evil generated sales of $9.5 million for third place.

Transformers: Age of Extinction has enjoyed a huge worldwide reception, generating more than $212 million in China alone, where it had a flashy star-studded premiere. The film has generated more than $575 million globally, according to box office tracking firm Rentrak.

Tammy fell short of industry experts' $24 million estimate on the heels of weak reviews. The film, which received a "fresh" rating from only 29 of 111 reviewers tabulated by Rotten Tomatoes, was written by McCarthy and her husband Ben Falcone, who also directed.

The movie, made for a relatively inexpensive $20 million, features a high voltage cast including Susan Sarandon as Tammy's grandmother, Dan Aykroyd as her father and Kathy Bates as a cousin.

Deliver Us From Evil stars Australian actor Eric Bana as a New York City cop who solves a case which he believes involves the devil. The movie is based on the investigative experiences of New York policeman Ralph Sarchie, who developed a knowledge of demonology which he used in many cases.

The buddy comedy 22 Jump Street, starring Jonah Hill and Channing Tatum as undercover cops in college, took the No. 4 spot with ticket sales of $9.4 million in its fourth weekend in movie theatres. It has totalled nearly $159 million at the box office, according to Rentrak.

Rounding out the top five, animated How to Train Your Dragon 2 took in $8.75 million, ahead of the PG-rated action adventure Earth to Echo which totalled $8.25 million. The movie tells the story of three young friends who are directed by signals on their cell phones to a small friendly alien robot that they need to help find his way home.

Paramount Pictures, a unit of Viacom, distributed Transformers: Age of Extinction. Tammy was released by Time Warner's studio Warner Brothers. Sony distributed Deliver Us from Evil and 22 Jump Street. Earth to Echo was distributed by Relativity Media.
