The Olympics are in Paris, but Hollywood seems to be taking over with yet another American star reportedly set to make a major appearance.

Tom Cruise is among a host of stars who flew in to watch the Games in person, along with the likes of ex-wife Nicole Kidman, Greta Gerwig, and Steven Spielberg.

But the rumour mill is churning out that Cruise will be more than a spectator.

The 62-year-old action star will reportedly take part in the closing ceremony on August 12 (AEST), where the Olympic flag will be handed over to 2028 host Los Angeles.

Details have been kept tightly under wraps, but media report Cruise will rappel down from the top of this year’s Olympic Stadium, Stade de France.

Although Cruise’s fondness for performing his own stunts is well-known, the scale of the State de France act may require him to use a stunt double to actually descend from the roof.

Cruise will reportedly to land on the stadium field while carrying the Olympic flag before a two-minute pre-taped segment featuring the actor performing in both Paris and Los Angeles will be aired.

These pre-filmed antics will likely include Cruise jumping off the iconic Hollywood sign, a stunt which he was captured filming in March.

The actor was reportedly the driving force behind his Olympic appearance, being the one to approach the International Olympic Committee (IOC) about bridging the 2024 and 2028 Games.

The IOC is yet to confirm Cruise’s involvement in the Closing Ceremony.

This would not be Cruise’s first time taking centre stage at an Olympics event; the actor was one of the torch bearers in Los Angeles ahead of the 2004 Athens Games.

Cruise has been a fixture at the Paris Olympics since the opening weekend, sitting in the audience for events such as swimming and gymnastics.

If the rumours are true,  the Paris Games would end as they started, having kicked off with some Hollywood glamour courtesy of performances from the likes of Lady Gaga.

Opening Ceremony director Thomas Jolly will also take the lead over the Closing Ceremony, which will be held indoors at the State de France after the Games were launched along the Seine on an unfortunately-rainy day.

For the closing event, the Stade de France will be transformed into a theatre with over one hundred performers, acrobats, dancers and circus artists, complemented by musical performances.
