Marvel's mantra for its cinematic universe has always been "It's all connected" - but with a widening gulf between movies and TV, some fans have started to question that. Now, Marvel Studios president Kevin Feige has reiterated the idea that there's only one MCU. What's more, he says that Mavel's movies and TV will crossover - he just doesn't know when.
Feige told i09 that Marvel's movie and TV universes weren't "necessarily" separate, before clarifying “The future’s a long time. So, the truth is, I don’t really know, but there are a lot of TV shows being made, and hopefully we’ll continue to make a lot of movies. At some point, there’s going to be a crossover. Crossover, repetition, or something.”
One of Marvel's top TV characters, Agents of S.H.I.E.L.D.'s Agent Coulson, debuted as part of the film universe before taking the lead role in the MCU's first TV venture, playing a critical role in Avengers. The Iron Man armor, as well as Samuel L. Jackson's Nick Fury, Jaimie Alexander's Sif, and Cobie Smulders' Maria Hill, appeared briefly in the show, but no substantial crossover has been done to date.
Some fans have speculated that Coulson could make an appearance in Avengers: Infinity War or its still untitled sequel, but no plans for such a crossover or cameo have been confirmed.
