Marvel Studios President Kevin Feige says that Spider-Man and Venom are "likely" to crossover in film at some point. While at a press event for Spider-Man: Far From Home, the long-time Marvel producer answered a question about the possibility.
"I think probably it's up to Sony. Sony has both those characters and, has Venom in their world," Feige told CinemaBlend. "I don't know what their plans are for another Venom or if they’re doing that. But it seems likely at some point."
While that might seem surprising, it isn't. Sony, which have owned Spider-Man and Venom's film rights since 1999, have already had the two character crossover before - in 2007's Spider-Man 3. And now here in 2019, Sony still owns the film rights to both characters - although they have allowed Marvel to use Spider-Man in their MCU films and to produce Spider-Man films for Sony.
Sony continues to make their own Spider-Man films, as evidenced by 2018's Spider-Man: Into the Spider-Verse animated film. And from how Feige presented the situation above, Sony could choose to use Spider-Man again in live-action in a crossover with their Venom franchise.
And while Feige said he doesn't know if Sony plans do to another Venom movie, a sequel has been announced for release October 2, 2020.
