If you're in London, you might want to participate in The Gillian Anderson London Charity Walk on Saturday 23 March at 10.30am.
It will start at The Royal Court in Sloane Square where Gillian performed The Sweetest Swing in Baseball and end at Crouch End where she spent her childhood.
They'll be taking in several Gillian-related sights along the way.
For more information, follow them on Twitter and visit their blog.
If you would like to donate or sponsor any of the walkers, you may do so at JustGiving.
This event will benefit SA-YES.
