Since it involves a massive cast of superheroes, fans have speculated that the two-part "Avengers: Infinity War" film could be a big enough event to bring together superheroes from all of Marvel's disparate franchises -- including those on television.

Specifically, fans are eager to see the heroes from Netflix's Defenders franchise (Daredevil, Jessica Jones, Luke Cage and Iron Fist) appear in the films alongside the big screen Avengers. Entertainment Tonight talked to "Daredevil" star Charlie Cox about this desire and the likelihood that his Man without Fear will be among the heroes assembled in "Infinity War."

"Marvel TV and Marvel Studios are two very different things," said Cox. "So even if the character were to appear in that film, that doesn't necessarily mean that I would appear in that film. I will pick a fight with the guy that they choose!... So that would be a dream, but that's not something that has been discussed."

Crossovers between Marvel Studios and Marvel Television are not unheard of, however. A number of movie characters have appeared on the ABC series "Agents of S.H.I.E.L.D." and "Agent Carter," including Howard Stark, Nick Fury, Sif, Maria Hill, Jasper Sitwell, Jim Morita and Dum Dum Dugan. The leads of both of those series, Agent Coulson and Agent Carter, also come from the films.

But so far, crossovers have not gone in reverse and no TV characters have appeared in the films. Clark Gregg, who plays Coulson in "S.H.I.E.L.D.," recently remarked that he thinks the upcoming "Inhumans" feature film will be free from the Inhuman continuity that's been established on television -- although he clarified that that's just an assumption and not an official mandate.

Netflix's "Daredevil" returns for season two on March 18; "Avengers: Infinity War - Part 1" opens May 4, 2018; "Part 2" opens May 3, 2019.
