Helen Mirren is arriving in style.
Mirren opted out of the standard town car or limo when it came time to arrive at the Rome premiere of her new movie Winchester on Monday, taking a custom bus instead.
The Oscar-winning actress took to Instagram on Wednesday to show off her unconventional ride.
“Arriving at the premiere for Winchester in Rome… by bus!” she captioned the above photo.
In the pic, Mirren is seen sitting on the bus as she pulled up to the red carpet. The custom black bus was decorated with lace in honor her character in the upcoming horror flick.
Once on the carpet, Mirren showed off her ageless style in a long red dress with bedazzles sleeves.
Winchester is based on the true story of Sarah Winchester (Mirren), a woman who was convinced that she was being haunted by the ghosts of people who were killed by the famous rifle that her family manufactured. After the sudden deaths of her husband and child, she threw herself into never-ending construction on her sprawling mansion — which features stairways to nowhere and doors that open onto walls — to appease the spirits.

“I don’t believe in ghosts, but I do believe people can be haunted, and Sarah Winchester is a haunted person,” Mirren, 72, previously told PEOPLE. “That was the appeal in the role.”
Winchester is in theaters now.
