His acting arc followed that of many of his British peers. He studied drama (at the Guildhall School of Music and Drama), performed in repertory theater, and tried his hand at Hollywood (with small roles in The Man in the Iron Mask and Laurel & Hardy's A Chump at Oxford). In 1948, he landed his best role to date as Osric in Olivier's Hamlet (1948), which featured another future Hammer star, Christopher Lee, in a bit part.
That didn't lead to bigger film roles, but did result in steady work in radio and early television. He achieved small screen success in fare such as a six-part Pride and Prejudice (as Mr. Darcy) and The Creature, an episode of the BBC Sunday-Night Theatre written by Nigel Kneale (and eventually adapted for the screen as The Abominable Snowman of the Himalayas starring Cushing). When Hammer's producers decided to make a Frankenstein film--which focused on the doctor, not the monster--they knew who they wanted.

In addition to his Hammer roles, Cushing also played Dr. Who in two big screen adaptations and was introduced to a whole new generation of moviegoers as Grand Moff Tarkin in Star Wars (aka Star Wars Episode IV: A New Hope).
His wife of 27 years, Helen Cushing, died in 1971, causing Cushing to withdraw from Blood from the Mummy's Tomb. He eventually returned to acting and was awarded the Order of the Britisth Empire in 1989. When he died five years later, colleagues and critics sang his praises as a fine gentleman, a loyal friend, and an underrated, exceptional actor.
