Tom Cruise meets Ukranian President Volodymyr Zelensky

Ukrainian leader Volodymyr Zelensky welcomed Tom Cruise to Kiev to discuss locations for one of the Hollywood superstar's new film projects, the presidency said Tuesday.

Zelensky, who was a popular comedian until his shock presidential election win this spring, told the 57-year-old actor about his own experiences in the cinema, the press service said.

It was not revealed whether the pair discussed the president's current role in a real-life drama: the scandal that has launched impeachment proceedings against US leader Donald Trump.

Photos showed the Ukrainian president beaming as he stood by the casually dressed blockbuster star in an official meeting room on Monday.

"During the meeting, Tom Cruise informed Volodymyr Zelensky that he was interested in Ukrainian locations for the shooting of one of his new film projects," the presidency said.

Earlier Cruise was spotted on the Soviet-era Kiev subway.

Some commentators criticised Zelensky for meeting the actor rather than focusing on his own mission impossible: tackling corruption and ending the war with Russia-backed separatists in the country's east.

Last month, the 41-year-old leader met Hollywood actors Mila Kunis, Ashton Kutcher and Robin Wright at an event in Kiev.

Others joked about the real reason for Cruise's visit.

"Tom Cruise came here to prepare for the role of Volodymyr Zelensky in a new movie about Trump's impeachment," blogger Petro Terentiev wrote on his Facebook page.

Trump is accused of pressuring Zelensky on July 25 to supply dirt on former US vice president Joe Biden, the favourite to represent Democrats against Trump in the 2020 presidential election.
