Martine McCutcheon has revealed she feared she would knock Hugh Grant unconscious on her first day filming Love Actually.
The former EastEnders star plays the tea lady who falls in love with Grant's prime minister in the 2003 Christmas film.
"Our first day of filming was actually filming the last scene which was the Heathrow scene and that was wonderful," she said.
"I was really nervous because I had to run and jump on Hugh, that was my first scene, and I was thinking 'Oh my God, I'm going to kill him'.
"He was like 'Come on, go for it', and I was so nervous because I had never had to jump on anybody in a scene in my life.
"Now as I do it, it's with the heartthrob that is Hugh Grant, in front of everybody, in front of all these amazing actors, and what if I knock him out? What if I do something wrong?
"Every time I ran up to do it, I stopped.
"Hugh called me Teeny, and he was like 'Come on Teeny, you can do it', and I was so scared I was going to hurt him or knock him over or something.
"Luckily, everything went great and we did good, he was fine, he can handle it. He makes it all look effortless."
McCutcheon is currently starring in a campaign for a doorstep greetings service inspired by the film, in which she recreates Andrew Lincoln's famous scene when he declares his love for Keira Knightley on flash cards.
Now TV's Greetings Gram service allows people to send their loved ones a free, personalised, socially-distanced doorstep message printed on cards and performed by a messenger.
"Over the years I've been asked to do tons of things related to Love Actually, but I just felt this year more than ever people need that human contact and human connection," McCutcheon said.
"What has been so lovely about Love Actually is it has just got a timeless quality to it and I think people forget just how much time has gone by.
"It's been wonderful for me because every Christmas, people have that reminder of you that a lot of actors and actresses don't have and it's been a blessing.
"I still pinch myself that I was in that movie with such an amazing stellar cast and I made some lovely friends too, it was really brilliant.
"We knew we were making something special and we were all so excited, but I don't think we thought it would be this much of a timeless classic at Christmas."
