Dawn of the Planet of the Apes” is leading ticket pre-sales going into a fiercely competitive weekend at the box office.

The post-apocalyptic thriller holds the top spot, according to Fandango, but “The Purge: Anarchy” is also showing its muscle. The film is the year’s biggest pre-selling horror movie, selling more tickets than such chillers as “Paranormal Activity: The Marked Ones” and “Deliver Us from Evil” and is also outpacing sales of the first “Purge” movie at a similar point in its sales cycle. “The Purge” racked up $34 million when it debuted last summer.

Coming in at third and fourth place are “Planes: Fire & Rescue” and “Sex Tape,” respectively. Fandango does not provide figures for the volume of tickets sold.

The other major online ticketer, MovieTickets.com, measures daily sales instead of weekend pre-sales, but reports that “Dawn of the Planet of the Apes” was its strongest title on Wednesday, accounting for 22% of all tickets moved. Tied for second place were the indie darling “Boyhood” and the “Planes” sequel, with 11% of tickets sold. “The Purge: Anarchy” was in fourth place with 8% of tickets sold, followed by “Transformers: Age of Extinction” with 5%.

Most analysts expect that “Dawn of the Planet of the Apes” will hold the top spot at the box office for the second weekend in a row. It debuted to $72.6 million last weekend on the strength of glowing reviews.
