Very early on in development , Andy Park created a visual sequence to sell the concept of Deadpool arriving in the Marvel Cinematic Universe . " In the VisDev department , we work on things so early , even before preproduction , " Park says . " Sometimes we're just doing high - level Ideation , blue - sky designs . There was no script - we didn't know what the movie was going to be about . The minimal information we had was that there was going to be some multiversal component , because obviously Deadpool is from a different universe . I came up with one idea that could be in the movie or could be used for marketing . My pitch was a black screen , then the text ' Deadpool enters the MCU , but it goes to this comic book image . And a caption says , ' Marvel Comics Universe , and you see Deadpool swearing , but there's this Comics Code Authority seal covering it up . Because of my background as a Marvel Comics fan and then eventually as a comic book artist , I had to pay homage to my roots with this - so , Captain America is drawn in a Jack Kirby style , Black Widow is drown in a Jim Lee style , Thor is a Walter Simonson style ; Hulk , Sal Buscema ; Iron Man , Mark Bright / Bob Layton ; Hawkeye , John Byrne , and Deadpool , of course , is Rob Liefeld . And , in my pitch , the screen goes to black again , and the text says , " Deadpool enters the MCRU - ond it's revealed as the Marvel Comics Realistic Universe , with this Alex Ross painting that I added Deadpool to . Because , before the movies , Alex Ross was as close as you could get to realism . And Deadpool's in the corner , saying , ' Almost , but not quite . ' And then , finally , we have ' Deadpool enters the Marvel Cinematic Universe , ' and it goes to the iconic shot of the Avengers in the New York bottle , all looking up at the Chitouri , with Deadpool in there , saying , " That's more like it ! It was just a fun idea to convey the concept of Deadpool universe - hopping and how there are a million different ways that Deadpool could come into this universe . It really got the imaginations of everyone firing and thinking up crazy things that could happen with this character in the MCU . "
