Updated June 26, 2019 at 11:02 a.m. Eastern: BoxOfficeMojo estimates that North American theaters will double the number of screens Avengers: Endgame will be shown in this weekend for the planned 'Bring Back' re-release.
According to the box office data tracking site, Avengers: Endgame will be adding nearly 1000 screens this weekend in North America for an estimate of 1950+ - well over the estimated 985 screens it played on over last weekend.
By BOM's most recent sales estimates, Endgame is $36.9 million shy of matching Avatar's record-setting $2.787 billion box office from 2009-2010. When Avatar was re-released in a similar fashion, it was shown in an estimated 812 theaters at its peak.
Updated June 25, 2019, 6:30 P.M.: Tickets for new, additional showings of the 'Bring Back' version of Avengers: Endgame with new content are being added to movie ticketing apps like Fandango, with tickets available for shows starting June 28.
Exhibition giant AMC seems to be adding new shows throughout the day and lists Wednesday as the day their venues will update with all showings for films on Friday and beyond.
Original Story: This weekend's Avengers: Endgame theatrical re-release will include an "unfinished" deleted scene, an intro video from co-director Anthony Russo, a sneak peek at Spider-Man: Far From Home, and a chance to get an exclusive poster (while supplies last). Marvel Studios revealed these details (and that poster) on their Twitter page, encouraging fans to use Fandango for tickets - although tickets are yet to be available on that retailer's website.
This re-release comes nine days before that follow-up, Spider-Man: Far From Home, hits theaters.
At the same time, Endgame's global box office totals are now just $37.2 million shy of the record-setting Avatar - and this re-release would work to help this fourth Avengers film surpass that goal. Avatar was similarly re-released theatrically a few months after its initial release, with added scenes and content.
The Avengers: Endgame re-release is scheduled to begin in theaters June 28.
