The hardest scene to do in the movie was when I had to swim across the Orange River about 5 times, then run up a hill of beach sand at speed, get to the top, and then do a really emotional scene

Playing Elizabeth Taylor was probably the hardest job I’ve ever done.

I find that in every new film – whether in terms of becoming a new character or more generally the shooting or production – I’m rarely working with the same people or in the similar situations. Sometimes the director is someone I haven’t worked with before, or the actors are different and the stories we are telling are different, so overall every role is kind of challenging but attractive at the same time. There were some roles that I found either mentally or physically challenging but I would find it hard to pinpoint one specific role that I found more challenging than any other. I guess that understanding each character is the most challenging for me.

My experience being on set, since I was a kid, is having a shorthand with a lot of the crew that have been around throughout my movie career. And I had a clear vision for the story that I wanted to tell, because I’ve been marinating on it and developing it for such a long time. It was the most challenging thing that I’ve ever done, by far. Daily, I was pushing myself to new limits, learning how to communicate and get what’s in your head out, and have other people pick up on that passion and enthusiasm, so that they want to execute your vision to the best of their ability. That’s not an easy task to do.

I stopped in my tracks when that thought came into my mind, that hiking the PCT was the hardest thing I’d ever done. Immediately, I amended the thought. Watching my mother die and having to live without her, that was the hardest thing I’d ever done. Leaving Paul and destroying our marriage and life as I knew it for the simple and inexplicable reason that I felt I had to — that had been hard as well. But hiking the PCT was hard in a different way. In a way that made the other hardest things the tiniest bit less hard.

The most difficult thing is the decision to act. The rest is merely tenacity. The fears are paper tigers. You can do anything you decide to do. You can act to change and control your life and the procedure. The process is its own reward.

There are so many challenges! Production is hard! There are challenges from the storytelling to the casting to the funding, to power supply, to distribution. Just name it! Every step is a challenge but we’ll continue to do what we do notwithstanding.

Every role I have played have been challenging for me. I play every role in order for the role to be outstanding irrespective of how simple it might seem. The simpler the role, the more challenging it is for me. Other actors might have played similar roles but I always strive to make mine different. I get very apprehensive each time I get a new script because then I have the task of interpreting it in a unique way.

The most difficult thing about Time, I have learned, is doing it.

Life is full of challenges and I encountered so many obstacles when I started acting

It’s been one of the greatest acting challenges of my life,

The Lookout was by far the hardest thing I've ever done. Partially because both Brick and Mysterious Skin were four to five week shoots, and The Lookout was nine or 10. So there's the marathon aspect, as well as the fact that Chris Pratt is having a harder go of it than either of the other two characters ever did. You know, waking up in the morning is difficult for him. Putting a sentence together is difficult for him. Getting dressed properly, driving a car, all these things. He can do them fine, but it's just much harder than it is for a normal person, so I had to try to make it hard for myself somehow. So it was challenging.

The hardest thing is always getting to the starting line and having the courage to do it. Most adventures fail because they are never done.

Filmmaking is hard work, and there are plenty of times when you're just exhausted, and you haven't slept in a while, and you're just watching, and you're looking at something, and you're thinking, "Man, this is not going to work, this is going to be the stupidest thing."
