Although details mostly remain secret regarding Friday night’s opening ceremony of the Summer Olympics in London, nurses are expected to have a prominent role during the performance.

Real-life nurses — not actors, according to BBC News — will perform a tribute to the National Health Service, which was founded in 1948 to provide free healthcare for all British citizens. The NHS helps make the country "unique," said Sebastian Coe, chairman of the London Games and a former track-and-field gold medalist.

The Daily Mirror, which obtained images of a dress rehearsal, reported that patients will be "jumping on giant hospital beds surrounded by nurses" during a portion of the ceremony.

Danny Boyle, the Oscar-winning director of Slumdog Millionaire, is artistic director for the ceremony, which can be seen on a tape-delay basis Friday night in primetime on NBC.
