Ryan Gosling is busy promoting his new movie Project Hail Mary in the UK!

The 45-year-old actor was seen arriving at BBC Studios in London on Tuesday (March 10).

He looked casual yet still stylish, wearing a camo Randy’s trucker hat, a plaid shirt jacket, light-wash jeans, aviator sunglasses, and what appears to be Red Wing Moc shoes.

Ryan has been out and about quite a bit lately to promote his sci-fi film.

The actor hosted Saturday Night Live again over the past weekend and his latest gig featured a surprise appearance from a beloved musician! He and his longtime partner Eva Mendes also appeared together on The Tonight Show last week.
