The Lion Inside

Venue

Unicorn Theatre

NO MATTER YOUR SIZE, WE ALL HAVE A MOUSE AND A LION INSIDE

A bestselling story about confidence, self-esteem, and a shy little mouse who sets out on a journey to find his roar. In a dry dusty place where the sand sparkled gold, stood a mighty flat rock, all craggy and old. And under that rock in a tinyful house, lived the littlest, quietest, meekest brown mouse.

Fed up of being ignored and forgotten by the other animals, Mouse wishes he could roar like Lion. But, as he discovers, even the biggest, bossiest people are scared sometimes … and even the smallest creatures can have the heart of a lion!

Based on the bestselling story by Rachel Bright & Jim Field, this brand-new adaptation for stage is directed by Sarah Punshon (The Jungle Book), with music and lyrics by Eamonn O’Dwyer (Brief Encounter).

A Unicorn Theatre co-production with Rose Theatre, Nicoll Entertainment, Curve and MAST Mayflower Studios.

With special thanks to Charles Holloway OBE, Weston Theatre Season Partner.
