Jessica Chastain thinks Matthew McConaughey is "gorgeous".

The 37-year-old flame-haired beauty told E! News: "It was A Time to Kill. The closing speech and he's the defence attorney and he stops and he kind of puts his hand on his face and he chokes back his emotions and I remember watching that moment.

"Before that film, I thought, 'Oh, that man's gorgeous,' and then when I saw that it was, 'Yes, he's gorgeous, but he's an actor. That was in the beginning and I've been a fan ever since."

There was no shortage of praise for the 'True Detective' actor at the star-studded event.

His 'Mud' co-star Reese Witherspoon also paid homage to the well-loved actor and admitted she could "watch him all day".

She explained: "He's handsome and he's got talent. He's got what my friend calls a 'two-hour face'--you want to watch him for two hours. He might even have a 'six-hour face.' That hasn't been tested yet. Well, it has, hasn't it with True Detective? You could watch him all day."

US talk show host Jimmy Kimmel even joked that watching handsome Matthew on screen had altered his sexual orientation.

He said: "I've learned a lot from Matthew from watching his movies over the years. One thing I've learned is that I'm bi-curious."
