Ty opted for a more casual look as he smiled for the camera with his sister.

The teen rocked an oversized black and blue leather jacket, black hoodie, matching joggers and a pair of smart boots.

Other famous faces who attended the event include Jamie Dornan, Dame Judi Dench and Lara McDonnell.

The film will follow the lives of a young boy called Buddy and his troubles growing up in Belfast, Northern Ireland in the 60s.

Belfast will be released in the US next month, but UK fans will have to wait until 25 February 2022.

This isn't the first time Olive has been on our screens.

At just two-years-old she landed her first ever role in The Five(ish) Doctors Reboot as John Barrowman's daughter in 2013.

Ty has also starred in a number of TV shows and films including Tolkien and War of the Worlds.

The two also have three younger siblings Wilfred, eight, Doris, six, and two-year-old Birdie.

David and wife Georgia tied the knot in 2011.
