Question: does mikasa die in the live action movie

Answer: No, Having survived the earlier attack, Kubal attempts to stop the group but is shot by Sasha, forcing him to transform into the Colossal Titan. As Eren, Jean, and Mikasa battle the Colossal Titan, Shikishima reappears in his Titan form and sacrifices himself by lodging the bomb into the Colossal Titan's mouth, killing them both. The detonation successfully closes the hole in the wall and Eren and Mikasa stand at the top of the wall overlooking the ocean.
