Braeden, who suffers from bronchomalacia, and his family were flown to Los Angeles by the For the Win Project organization so he could bust ghosts for a day and make his own “Ghostbusters” movie trailer.

As a special treat for Braeden, one of the original Ghostbusters makes a cameo. Dan Aykroyd reprises his role as Ray Stanz and calls Braeden to come join the team.

He even got to use props from the 1984 movie, which came in handy when he had to fight the Stay Puft Marshmallow Man.

Braeden also got his own poster and video messages from the directors of both the 1984 and 2016 “Ghostbusters” films, Ivan Reitman and Paul Feig.
