Your spider-sense should still be tingling from the official start of production on "Avengers: Infinity War." (Maybe that pic shows what happens to your face when the sense gets really strong.) Marvel shared a behind-the-scenes video from set late Friday night, then several stars followed-up with an amazing Facebook Live Q&A on Robert Downey Jr.'s (Tony Stark/Iron Man) timeline.

The Facebook video features cameos from directors Joe and Anthony Russo, plus Downey's "Infinity" co-stars Chris Pratt (Peter Quill/Star-Lord), and -- also doing double-duty as the "camera guy" -- Tom Holland (Peter Parker/Spider-Man). Those three actors were also featured in Marvel's first-look video (see below) so it seems safe to say they had the bulk of the shooting work on Friday.

The "camera guy" read off some fan questions for RDJ before the directors talked a bit, then "camera guy" revealed himself to be Tom Holland in motion capture visual effects mode.

What excites you most about being back with the Avengers?
RDJ: "I can't give too much away, but this literally feels like the second greatest story ever told, and there's so many characters, and so many interesting stories, so many surprises."

Are you and Captain America still not getting along?
RDJ: "That is correct. He's on my s-list."

Watch the whole thing:

Here's the first look at "Infinity War," which Marvel shared Friday to celebrate the start of production: The stars were just as impressed as fans:


"Avengers: Infinity War" will be released May 4, 2018, and "the second part" (Marvel's words) will be released May 3, 2019.
