Prince William

The 35-year-old royal will be attending a special screening of the iconic broadcaster's upcoming wildlife documentary series 'Blue Planet II' at the BFI Imax Cinema at Waterloo next Wednesday (27.09.17).

William will get the chance to meet the 91-year-old naturalist as well as composer Hans Zimmer and selected guests and schoolchildren who have also been invited to the special screening.

Before the screening starts, the royal - who is currently expecting his third child with his wife Catherine, Duchess of Cambridge - will meet with schoolchildren from Lionel Primary School in Brentford as they take part in quizzes and see some of the technology used to film the series, including the megadome camera and a live demonstration of the full breathing apparatus used for underwater filming.

William and the other guests will then be treated to a sneak preview of the first episode of 'Blue Planet II', which is set to air on BBC One later this year.

Prince William will be carrying out the engagement on is own, as his pregnant wife Catherine, also 35, is currently suffering with Hyperemesis Gravidarum - a debilitating form of serious morning sickness - as she did with her two previous pregnancies when carrying four-year-old Prince George and two-year-old Princess Charlotte.

Meanwhile, the couple are reportedly set to pick a "down to earth" moniker to bestow on their unborn tot.

Global naming director at Siegel + Gale, Christian Turner, said recently: "The key consideration when naming a royal baby is the fine balance between tradition and accessibility.

"The Duke and Duchess of Cambridge will want the fifth-in-line to the throne to bear a name worthy of such weight, and it's therefore likely they will choose a solid, traditional name with strong links to royalty.

"At the same time, they won't want to appear old-fashioned or haughty, so choosing a name the public can embrace is equally important.

"George and Charlotte are excellent examples of names that strike the balance perfectly; royal by tradition, solid in heritage, both names have enjoyed a resurgence over the last decade, and it's not uncommon to hear either name being called in the local playground. This is common of the style of this generation of royals, who want to be more down-to-earth than their predecessors."
