London, Jul 22 (IANS): Actor Armie Hammer is all praise for his "The Lone Ranger" co-star Johnny Depp and said that working with him was better than anything he could have ever imagined.

Hammer, 26, attended the movie's premiere at the Odeon, Leicester Square July 21.

"Working with Johnny was exactly how you would think except better because he's cooler than you think," Bang Showbiz quoted Hammer as saying.

While the actor was proficient at horse-riding before shooting the action sequences, he admits that some of the stunts were a struggle for him.

"I already knew how to ride a horse so I was lucky I had a baseline but it's difficult learning how to ride a horse through a moving train," said Hammer.

"Some of the harder stuff to get through was when we were buried in the desert up to our necks. Yeah, you'll see. We were buried up to our necks for probably a day and a half," he added.

Director Gore Verbinsky also attended the premiere, along with actors Ruth Wilson, Tom Wilkinson and Harry Treadaway.
