Cast in the trailer for Gritos en la oscuridad (2006) as Michelle Trachtenberg's character. The movie was so gory that in order to show the trailer on American television, all the scenes that would be used needed to be filmed again. Michelle was unavailable so the production company thought it could get away with casting a new actress even though Jillian is not actually in the film. In the trailer she gets thrown off a snowy roof and pierced by a Christmas tree, stuck having to chop her friend out of a frozen lake in the snow and has to open a deadly Christmas gift.
