The actor supports the cause.

Today, the number of people who showed up to support March for Choice was overwhelming. There is strength in numbers, and after today hopefully people won't feel alone in their struggles with the 8th amendment. Thousand's of people showed up today despite the less that perfect weather. Several well-known people stepped out today to show their support. Cork actor Cillian Murphy was spotted at the march today. https://twitter.com/elehutch/status/779691049858035712?ref_src=twsrc%5Etfw While each person who showed up today is equally important, it is also crucial that well-known Irish figures, who have a large influence spread the message of equality. It is important to see men as well as women, and people of all ages, from all over, at these marches to prove that this is not only a feminist issue, but a human one. https://twitter.com/PantiBliss/status/779685539691761664 https://twitter.com/RebeccahLouise/status/779690391134146560 https://twitter.com/Mc1988/status/779680642669961216
