'Avengers: Endgame' pre-sales are 5x higher than pre-sales for 'Infinity War'

Looks like killing off half the cast of Infinity War is paying off big time for Marvel.

After just one week of pre-sales, Avengers: Endgame is reportedly outselling Avengers: Infinity War 5 to 1 on Fandango. Earning over $2 billion worldwide during its initial release, Infinity War is the second highest-grossing Marvel film to hit theaters -- second only to the unprecedented success of Black Panther.

The highly-anticipated final Avengers installment has also beaten the records for both highest first day and highest first week of pre-sales on Fandango, accolades previously held by Star Wars: The Force Awakens.

On the first day of Endgame ticket sales, users flocked to online box offices at such high rates that the AMC Theaters site temporarily went down -- and Fandango was forced to put user sessions "on pause" while they sorted out site demand.

Fandango reports thousands of Endgame showings are already sold out across the country. Many theaters are scrambling to meet demand, adding showtimes as early as 4:00 am and 6:30 am on opening day.

Worried you won't snag a seat? Don't be. According to Fandango's Managing Editor Erik Davis, there are still "plenty of tickets available on Fandango for the year’s most anticipated movie."

Avengers: Endgame hits theaters April 26.
