Marvel Entertainment has released another trailer for Avengers: Age of Ultron, this time showcasing Black Widow’s teamwork skills. Marvel also announced the fan-chosen IMAX giveaway poster winner (pictured here).

The battle scenes are similar to the last TV spot (see “Quicksilver Speaks in New 'Avengers: Age of Ultron' Trailer”), but the scenes continues for a few seconds more, and toward the end, Black Widow shows off some fantastic driving skills to save Captain America.

Marvel hosted an IMAX poster design contest last week, where fans could choose which of four designs would be given away opening night to patrons of the first IMAX showing.  See all four potential designs in the gallery below.
