Emily Blunt

Emily Blunt had to "channel memories" of being drunk for her role in 'The Girl On The Train'.

The 33-year-old actress - who plays the lead role as Rachel Watson in the film adaptation of Paula Hawins' novel - has admitted she wasn't allowed to taste "a drop" of alcohol whilst shooting scenes for the thriller because she was pregnant with her second child at the time she was filming, and had to reflect on "distant memories" of having too many drinks to get into character.

Speaking to The Sun Online about her preparation for the role, which sees her character battle with alcoholism and memory loss whilst trying to piece together moments she witnessed Megan's murder whilst intoxicated, she said: "But for this movie I couldn't touch a drop [of alcohol], so I had to channel memories, that felt increasingly like distant memories, of drunkenness. And then I went home and stared at my bump.

And Emily has revealed there have been a "couple" of times where she has no recollection of the evening whilst she has been inebriated, similar to her character.

She explained: "I've had a couple of blackout drunk nights in my life, yes.

"Everyone seems so shocked when I say that but give me a break.

"Everyone's had a night like that.

"I've had a couple where I'm like, 'What happened? Oh my God, what did I say?' - where you have only the vaguest recollection of what you might have done.

"[But] I'm a really fun drunk."

And the star - who gave birth to her daughter Violet in July this year, and has two-year-old daughter Hazel with her husband John Krasinski - has revealed the recent release has "stretched" her acting ability.

She explained: "Playing Rachel has stretched me in ways that I haven't been stretched before. I had to flex muscles I've never accessed.

"Trying to understand this addictive personality, that sense of being unable to put one foot in front of the other without relying on a drink, has been an extraordinary experience."
