The $8.61 average outlay for a ticket in Q2 represents a 3.4% increase over the period last year, and is the highest quarterly price to date, according to data from the National Association of Theater Owners.

The increase largely reflects popularity of blockbusters led by "Jurassic World" and "Avengers: The Age of Ultron," which commanded top-dollar prices in 3D as well as Imax and other large screen venues. The two films accounted for 42% of the total box office revenues in the quarter for the 10 most popular films.

The new number tops the previous quarterly high of $8.38 set in the second quarter of 2013.
