Atom Tickets, a theatrical ticketing iOS and Android app, raised $50 million, in a funding round that included investments from Walt Disney Co and 20th Century Fox.

While currently only available in three cities in the US – Knoxville and Cookeville in Tennessee and Lima in Ohio – it plans to go nationwide later this year.

Movie-goers can use the service to purchase tickets and concessions, coordinate with and invite friends without having to pay for them, and jump queues at the venue.

The app also supports dynamic ticket pricing based on demand and provides reviews, trailers and synopses information.

Kevin Mayer, chief strategy officer of The Walt Disney Company, said Atom’s technology “not only adds value to the consumer, but also helps movie studios and theaters by providing deep consumer insights, advanced analytics, and concession and ticket couponing.”

Lionsgate, another investor, hopes the app will help fill the four billion seats that go unsold in theatres each year.

Established in 2014, Atom Tickets’ Series A funding was led by Lionsgate,  and $10 million was raised.
