Hollywood is remaking one of its most cherished traditions: the summer blockbuster. Unlike last year, when every summer weekend seemed to bring one or more mega-budget films, this year studios have spread out their most expensive entries for the warm weather months that traditionally make up roughly 40 percent of annual ticket sales. So far, moviegoers are lining up. Six films released since March 7 have passed or are nearing $100 million in U.S. and Canadian ticket sales, according to tracking firm Rentrak.

Marvel Entertainment has released another “Captain America: The Winter Soldier” deleted scene online. This one apparently teases on a possible Natasha Romanoff/Black Widow prequel.

Spoilers ahead.

In the second half of the film, just after Natasha (Scarlett Johansson) revealed Alexander Pierce’s (Robert Redford) dastardly plans to the senior S.H.I.E.L.D. officials, she has disabled security protocols and uploaded S.H.I.E.L.D. and Hydra data onto the Internet.

“To do this, none of your past is going to remain hidden,” Pierce told her. “Are you sure you’re ready for the world to see you as you really are?”

In the deleted scene, Pierce’s brief speech is a bit longer. Before asking Natasha if she’s prepared to be unmasked, he added the line, “No Budapest, Osaka and not the children’s ward.”

Natasha wasn’t fazed until Pierce mentioned the children’s ward.

After momentarily pausing in her work, she came back at him with, “Are you?”

Viewers may not know what really happened in Budapest, but they are aware of it because it was mentioned by Clint Barton/Hawkeye (Jeremy Renner) in the “Avengers” film.

Jump to 1:15 for the “Budapest” mention

But what was in children’s ward?

In the comics, Natasha was a trained spy from childhood as part of the then USSR’s Black Widow Ops program. That might explain the “children’s ward.”

As Slashfilm has questioned, perhaps the deleted scene was meant to tease Natasha’s back story in either a One Shot short film or a standalone feature film.

There have been talks about Marvel developing a standalone feature film starring a female superhero, and if there’s one character deserving to have her own film, it’s Black Widow.

Apart from the deleted scene above, Marvel also released two more cut scenes and a blooper reel earlier in August.
