OK, well they have been advertising it already, even if that
one trailer was new to the superbowl.
But no one talks about that one. It was just a movie ad, for a movie that had already been revealed for months and shoved down our throats. Further, there is really nothing about Sam Jackson in that ad where people would talk about him.
The Lawrence Fishburne ad was hyped, and one of the top ads that people were discussing.
The reporter knew it, Sam Jackson knew it, and the reporters crew knew it--you know that is what he was referring to when he looked to the side, got cues from his staff, and realized his mistake.
The statement: "The Marvel movie, the superbowl ad, Robo--" He was listing various appearances and projects that most people would realize were separate things. That ad was not a separate thing that he recently appeared in--it was a movie trailer: cobbled together to promote a film. It is not a separate script, it is not a separate paycheck, it is not in any way anything that was further promoting him as an actor.
