Star Wars Episode 1: The Phantom Menace - I'm Building a Droid
Right after Anakin invites the gang into his house Qui-Gon introduces himself to Shmi (Annie's mom) and sez "Im Qui-Gon Ginn" then he turns his head down to Jake Loydd and sez "Im building a droid" just as Anakin/Jake sez that same line. He was helping him out. So through the scene Liam Neeson is saying "Im Qui-Gon Ginn, Im building a droid. Your son was kind enough to offer us shelter."
