I was comvinced Tiny Vader was a she.  I saw the pink room and the baby doll, and no sister in sight and proclaimed “Tiny Darth Vader is a GIRL!”.  But alas, I was wrong.  Tiny Vader is played by the adorable and talented (how did he emote so much in a full costume?) 6 year old Max.

Of note: Like the “real” Darth Vader, Max depends on technology to keep him healthy – he has a pacemaker.
