I am working as a graphic designer for a small team of researchers in a national research organization. One of our team members is affectionately called "Baymax" from the film "Big Hero Six".
I am currently creating a promo video that demonstrates the technology we are working on. This video is interview style and I would like to have a title card that displays the researcher's name and then underneath that his internal nickname "Baymax". I am wondering though if this falls under fair use or if it is a bad idea.
