We round up the geek movie news on a big news day for Avengers: Endgame.

Advance ticket sales for Avengers: Endgame got off to a record-breaking start Tuesday, with major ticket sellers reporting record sales.  Fandango sold more tickets for Avengers: Endgame in the first six hours of pre-sales than for the previous record holder, Star Wars: The Force Awakens, in its first day, according to Variety.  Similarly, Atom Tickets said it sold four times as many tickets for Avengers: Endgame as it did for its previous record-holder, Aquaman, in less than half a day.   Theater chains AMC and Alamo Drafthouse reported websites unable to process ticket requests at times on Tuesday.

The number of showings per theater may be limited somewhat by the long running time of the movie, revealed to be around 3 hours this week according to an interview with co-director Anthony Russo by Fandango.

The hardest of hardcore Marvel fans can book the ultimate MCU experience at AMC:  a 59-hour marathon of all 22 of the Marvel Cinematic Universe films, beginning with Iron Man and ending with Captain Marvel, leading up to a one-hour-early premiere of Avengers: Endgame at theaters in New York, Los Angeles, and Chicago. Attendees will get marathon-only collectibles and a special concession offer.
