Sigourney

The debate was so distressing that I started clicking around and landed on PBS where they were showing an episode of Doc Martin guest starring… Sigourney Weaver?

Very soothing!

Turns out Sigourney is good friends with Doc Martin actress Selina Cadell:

I loved Selina as soon as we met in that London pub. We stayed in touch the old-fashioned way after that first summer in London, sending letters and postcards. When I found out I’d got the part of Ripley in Alien, I phoned my parents and then Selina. I was thrilled that I was going to be filming in London.

When you have a friend who’s also an actress, but is as generous and as well-balanced as Selina, then you can call them up and tell them about a great job. There were plenty of friends I wouldn’t have been able to call, because their first instinct would’ve been, “Why am I not getting a movie?” But I knew she’d be happy for me.

And:

I said, “Are you kidding? I’d love to!” They sent messages via Selina asking if I’d appear in series seven and again in series eight. Of course I did! I made Avatar rework their schedules so I could be here.

People expect me to behave in a grand manner, but it’s not like I’m John Travolta. Having a cameo in Doc Martin is a dream job for me. Cornwall is the most beautiful place. I’ve read every novel about it I can and I watch Poldark on my iPad.

…

I admire you British: when things get tough, you reach for humour. Not firearms. I’d love to live closer to Selina, but however far away she might be, she is always with me. When I’m working I start each day by listening to a tape she recorded for me ten years ago. She tells me how to relax, how to catch my breath. It’s my safe place.
