Tom Cruise has been in Prague looking for locations for his new film Mission Impossible 4.
The Hollywood A-lister was joined by director Brad Bird and the two were spotted spending a lot of time at a castle where they repeatedly climbed a flight of stairs in the foyer.
Prague Old Town is where Tom, 48, shot the first Mission Impossible movie in 1995, which was directed by Brian de Palma.
Jonathan Rhys Meyers and Simon Pegg are rumoured to star opposite Tom in the fourth installment, due for release in December 2011.
Other filming locations that have already been confirmed include British Colombia and Dubai.
Tom was joined in Prague by his wife Katie Holmes and their daughter Suri.
