When Titus is walking in the city to go his Lion King Audition, you can see a poster for Frozen the Musical. This scene is set in the 90s but Frozen wasn't on Broadway till 2016.
While watching Sliding Doors (1998) in 1998, Titus derisively calls Gwyneth Paltrow "Goopy" in reference to Goop, a company she founded in 2008.
