This week on Plan B, Sarina caught up with the one and only Colin Firth.
He spilled the beans on what brought him back to do the Mamma Mia sequel.
"It’s just irresistible to be with that team. It’s one of the most enjoyable experiences I have ever had. Those people really are my best friends and nothing would stop me".
He also added that he quite enjoys the singing part of it too.
"Normally I’d have compassion and confine myself to the shower but I love it. If I have to apologise afterwards, so be it.”
He also talked about why he isn't entertained by his own films, working on Mary Poppins Returns and what we can expect from Kingsman: The Golden Circle.
