20th Century Fox Logo
The TCF logo in the trailers is the same as the 2013 logo, but with added colour. However, in the movie, the 2006 logo is used (with no byline).
20 = green
th = purple
Century = red
Fox = yellow
Before the end credits, we see night going over Teletubbyland accompanied by "Three Gone" by Elmer Bernstein, but recorded and conducted 3 semitones higher.
At the very end of the movie, the Noo-Noo is tidying up when he sees us. Similar to the ending to Ferris Bueller's Day Off (1986).
