Tom Hiddleston was all smiles at an event to mark the launch of his Disney+ series Loki.

The British actor, 40, is reprising his role as the God of Mischief in the highly awaited standalone series, which will begin streaming the first of its six episodes on Wednesday.

Hiddleston has played the antihero in Marvel big-screen blockbusters such as Thor, Avengers: Infinity War and Avengers: Endgame.
