Marvel has rolled out the opening trailer for Avengers: Doomsday, and a packed roster turned up with Robert Downey Jr. confirmed as Doctor Doom. The video came out and it features a string of major names, though Spider-Man was left out of the lineup. Doctor Strange got little room, which had fans buzzing online. Seats become available next week, once the timing was settled. Pre-release noise is asking a straightforward question: can this lean cast pull Marvel out of its recent downturn? The studio is leaning hard on familiar faces, with Doom front and center. Trading strategies vary, with some analysts calling it a bounce-back. The clip leans on big set pieces. Fans dissected each shot. Demand may spike early. Marvel still has room to recover. The next drop is expected soon, and the reaction is far from final.
