Walker, Texas Ranger - Season 9 Episode 22 -

A show played largely for laughs (and with Walker not involved in the story; he has a few scenes checking in with Alex's obstetrician to try to find the sex of their upcoming baby): Trivette leads a group of Rangers backstage at Las Colinas Studios (and the actors' trailers for this show) to investigate skulduggery on a movie being filmed in Dallas.
