Hedlund got tips from Pitt on Troy
Garrett Hedlund has told how Brad Pitt taught him all about making movies.
The Unbroken actor made his big screen debut alongside the Hollywood star in 2004's Troy, and said Brad gave him lots of tips.
He told Flaunt magazine: "[Brad] helped me understand a lot of the technicalities that actual filmmaking involves, how broken up it can be just to shoot one scene, how many different angles and camera shots, and how to approach the scene with different colours of emotion each take."
Garrett, 29, said he has also learned from other co-stars including his Four Brothers colleague Mark Wahlberg.
He said the Transformers star was " hilarious to watch". "How he improvises throughout the film," he added.
He shared the screen with Viggo Mortsensen in On The Road, and told the mag: "[He] gave me a book of his photography and poetry during On The Road.
"It's great to see people that never lose touch with that creative side of themselves, to meet that artist that never ceases to see the world in a different way."
