London wants to ensure theatergoers do not receive a figurative surprise stab in the back by the violence depicted in its performance of William Shakespeare's The Tragedy of Julius Caesar.

Attendees are warned that the play about one of the most famous assassinations in history features "depictions of war, self-harm and suicide, contains violence, stage blood and weapons including guns and knives." The warning comes on the website for tickets for the play, which is set to run from July to September.

The admonishment has elicited criticism from some conservatives who argue it amounted to a trigger warning and panned the Globe, located on the site of Shakespeare’s original theater, for being "woke."

The play will also feature increased diversity in its casting with Marcus Junius Brutus, Caesar's male friend who assassinates him, being portrayed by Anna Crichlow, a black British actress.

The Tragedy of Julius Caesar was first performed in 1599 and has remained a critically acclaimed classic centuries later. Tickets for the performance at the Globe range from 25 to 62 pounds (or roughly $31.47 to $78.06 in U.S. currency).

"This Summer, we confront our own political landscape as Shakespeare’s epic tragedy Julius Caesar takes on startlingly new relevance in the Globe Theatre, and across the UK as part of Globe on Tour," a description for the play reads.

The leadership at the Globe has previously faced criticism for warnings about "upsetting" themes in ticket sales for last year's production of Romeo and Juliet, the Daily Mail reported.

“This production contains depictions of suicide, moments of violence, and references to drug use. It contains gunshot sound effects and the use of stage blood," the warning read. “If you have been affected by any of the issues raised in this production of Romeo and Juliet, please find details below of organizations offering advice and support.”
