Christopher Nolan’s space adventure “Interstellar” took in $3.5 million in the U.S. at late night shows Thursday, boosting its overall take to $4.85 million ahead of its wide release. The Thursday figure included $800,000 from 249 film and Imax sites.

The $3.5 million figure is in the same range as previews for “World War Z” at $3.6 million and “Inception” with $3 million.

Disney is also seeing a solid start for “Big Hero 6” with Thursday night preview showings generating $1.4 million.

That’s a notable improvement on the $1.2 million Tuesday night take for “Frozen” last November, in advance of its pre-Thanksgiving opening.

The toon’s haul is also well above preview grosses for Warner Bros.’ “The Lego Movie” at $400,000 and “Rio 2” at $375,000 earlier this year, as well as the $400,000 for midnight shows of “Wreck-It Ralph” in 2012.

The $1.4 million for “Big Hero 6” matches the Wednesday box office for “Interstellar” from a limited number of locations.

Both films are expected to pick up somewhere in the $55 million to $60 million range this weekend. Both films cost $165 million to produce.

Paramount Pictures, which is distributing “Interstellar” domestically, released the science-fiction epic in 249 theaters at mid-week, 42 of which are Imax screens.

“Interstellar” will expand this weekend to 3,561 locations, 369 of which will be in Imax. Warner Bros. is handling the foreign roll out and will debut the film in most major foreign territories, with the exception of Venezuela, China and Japan.

“Big Hero 6” is opening at 3,761 locations in the U.S.
