As Anakin walks the streets of Coruscant, there is a close up of a Dulok from the Star Wars: Ewoks (1985) cartoon. Moments later, a Cylon Centurion from Battlestar Galactica (1978) can be seen on the right hand side.
The astronaut holding a large animal on a leash visible on Coruscant is based on concept art seen on page 15 of "The Art of Star Wars: Episode II - Attack of the Clones (2002)". A large Aqualish that can be spotted a moment later is based on a picture on page 38 of the same book. The long snouted alien that notices Anakin and Padmé in the alley is based on a sketch by Nilo Rodis-Jamero seen on page 29 of The Art of Star Wars: Episode VI - Return of the Jedi (1983).
