Mellotronists

A few days ago I saw the film "I Am Sam" starring Michelle Pfeiffer and Sean 
Penn. The film uses several Beatle songs (covers, sung by others), mostly 
from their later period as a musical backdrop. I imagined myself to be 
hearing some tron flute in there somewhere. Alas, it was could well have been 
real flute. But does anybody know if a tron was ever used in these renditions 
of Beatle songs in this film?
