Rachel Weisz on Colin Farrell: His face was like doughy flesh when we first met and he'll always be that man to me
Actress Rachel Weisz said she will always associate Colin Farrell with his Lobster alter-ego as their new film premiered tonight at the BFI London Film Festival.
The Irish star, 39, had to pile on the pounds to play David in the unconventional love story, directed by Yorgos Lanthimos as his English-language debut, in which the pair play two people who fall in love.
Weisz, 45, said on the red carpet outside Vue West End cinema: "I'd never met Colin before. I met him when he had the increased weight and his face and his jawline were like doughy flesh, so he will always be David to me."
Farrell said he didn't enjoy the weight gain. "It was not really a joy because you're just eating for eight weeks. I didn't want to put on weight because I didn't want to work to lose it, so I was saying to Yorgos, 'What about if he's really thin?' Because I did want to alter my physicality somewhat."
The Lobster, also starring Olivia Colman, Ben Whishaw and Jessica Barden, feature characters staying at a hotel who have to find themselves a partner within 45 days in a life-or-death situation.
Weisz - whose character is described as Shortsighted Woman - said: "I don't think the plot of the film is to be taken seriously. It's very absurd.
"It's more about how we all live like sheep and we follow rules and nobody really steps out of line. It's a very original film about how hard it is to be original."
Farrell added: "Love at first sight is possible and it's a quicker time than that, but the film asks questions about aloneness, coupledom and singledom.
"People can make whatever decisions they want after they've seen the film. That's another way of saying, 'I don't know'."
Colman, who plays the hotel manager, said: "For some people it would be possible. It's not an ideal way of doing it, being forced into it. It's a fun notion."
Lanthimos said he is "proud" of his cast.
"I was anxious about how it would work out as it was mostly people I have never worked with or known before. But all of the actors were amazing, they gel together very well. It was a great experience."
Weisz also revealed how she has yet to see Spectre, the new 007 adventure starring her husband Daniel Craig as James Bond.
She added: "He finished filming Spectre in June, so I've had him back for a while now."
The Lobster opens in UK cinemas on Friday, October 16.
