A new production of Evita is being ridiculed for its 'woke' trigger warnings about 'loud music and sudden noises'.

The West End musical centres on Eva Peron, the wife of Argentine President Juan Perónm, whose life begins as a poor girl to a powerful political figure and beloved First Lady.

The show, fronted by Snow White actress Rachel Zegler as Eva, ends with her early death from cancer at age 33 and the show features songs like 'Don't Cry for Me Argentina'.

Audiences were alerted to the strobe lighting, flashing lights and haze.

But trigger warnings for shows have been blasted in the past by Sir Ian McKellen, 86, best known for his Gandalf role in 'The Lord of the Rings', as reported by The Sun .
