Is it possible that a trailer can make you feel giddy yet sad all at the same time?

In this trailer for The Imaginarium of Doctor Parnassus, we get to see Heath Ledger on the big screen for the final time. Although the project was put in limbo after the Oscar winner’s January 2008 death, the generosity of three fellow actors helped save the film.

Instead of scrapping the movie altogether, director Terry Gilliam (Brazil) recruited Johnny Depp, Jude Law and Colin Farrell for the adventure. The three men not only donated their time, they donated their fees to Matilda Ledger, Heath’s daughter.

Parnassus - also starring Christopher Plummer, Tom Waits, Verne Troyer and Lily Cole - opens on Oct. 16.
