For a TV series that features two Marvel characters that have appeared in numerous films, there’s still a lot of mystery that surrounds “The Falcon and the Winter Soldier.” Will Anthony Mackie’s Falcon become the new Captain America? What’s up with USAgent? And how does Zemo figure into all of this? We honestly don’t know what’s going to happen, as Marvel sure does love its secrecy. And according to writer Derek Kolstad, there are even more mysteries that we haven’t even speculated about already.

Speaking to the Script Apart podcast, Kolstad, who is probably best known for his work on the “John Wick” films, talked about his upcoming Marvel Studios series. While teasing what’s to come with “The Falcon and the Winter Soldier,” Kolstad actually hinted that there are even more surprise characters showing up than fans are prepared for.

“What I will say is that there are characters from the earliest Marvel movies that are coming back,” Kolstad said. “We’re layering them in and reinventing them in a way that’s gonna shift the storytelling structure. It’s fucking awesome.”

Apart from Zemo, who previously appeared in “Captain America: Civil War,” we know that the series will feature Batroc (from “Captain America: Winter Soldier”) and Sharon Carter (‘Winter Soldier’ and ‘Civil War’). But who else can we expect? Are we going all the way back to “The First Avenger?” We all know how Marvel loves to pepper in references to previous films, so the sky’s the limit.

Kolstad also talked about what it’s like to tackle a series featuring sidekicks. As mentioned, both Mackie and Sebastian Stan’s characters have been featured in quite a few Marvel films before, but they’ve always played second fiddle to Steve Rogers, aka Captain America. But now that Steve is no longer in the picture, it’s time for Falcon and the Winter Soldier to take center stage.

“I’m very proud of and honored by what it came to be,” he said. “Here’s what I’ll say: growing up, everyone would give someone like Robin shit. But Robin’s pretty badass, and became pretty badass in the comics. [We’re] taking secondary characters and putting them in the primary roles, and [as a result] they’re cooler. They’re more interesting. There’s more humanity, more longing, more suffering, and coming to grips with who and what they are.”

Previously, “The Falcon and the Winter Soldier” was supposed to arrive in August. However, due to COVID-19, that was delayed. With filming wrapping up now, finally, hopefully we’re going to see the new Disney+ series arrive in early 2021.
