'The Ministry of Ungentlemanly Warfare' Cast on Why Henry Cavill Is the Ultimate Gentleman (Exclusive)

The stars of Guy Ritchie's action-packed WWII caper spoke with ET about the leadership abilities of the handsome rogue.

In director Guy Ritchie's new high-octane World War II action caper, The Ministry of Ungentlemanly Warfare, Henry Cavill stars as the chaos-loving, explosion-happy leader of a ragtag band of government-sanctioned assassins and saboteurs tasked with doing their best to cripple the Nazi forces.

Cavill stars alongside Alan Ritchson, Henry Golding, Alex Pettyfer, Hero Fiennes Tiffin and Eiza González, as they play characters based on real-life WWII allied heroes fighting to stem the tide of fascism in the face of daunting odds.

Cavill, Golding, Pettyfer and Tiffin all recently sat down with ET's Nischelle Turner to discuss the forthcoming historical reimagining -- and how Cavill is the ultimate gentleman in real life.

"Gentleman is the right word, for sure. And it's because he has an unwavering commitment to the cause and energy and consistency and mood," Tiffin explained of his co-star. "[He has an] ability to just keep everybody up and keep the momentum going."

Tiffin added, "I've always noticed any time there's a conversation going on on set, I feel like Henry's got his eye out for anyone who's somewhat half involved in the conversation and will always ask their two cents."

"Henry has a way about him where it's about the quality and about coming together and there is no hierarchy," Pettyfer chimed in. "He brings a humbleness to the set with everyone."

Addressing Cavill directly, Pettyfer said, "It was an amazing honor, by the way, to be on this film with you because it's a learning curve to see how a number one treats everyone in the cast and crew. I got an email two weeks before I started filming from this man saying, 'I'm excited to collaborate with you.'"

According to Pettyfer, Cavill actually kept him safe from physical harm while shooting the film.

"He saved me from falling off a boat," Pettyfer recalled. "I nearly drowned! So I can officially say I've been saved by Henry. And I'm very grateful to be on this film with you."

"We have some very tiring days," Golding shared. "We have some very long shoots, half the time we barely know what we're doing. But to have somebody always first on set and last to leave again -- just little things like that really make a difference to the crew and the cast. It was a pleasure."

Moved by the appreciation from his co-stars, Cavill shared some praise of his own, expressing, "I think it was an enjoyable experience and it's all thanks to these guys and Guy [Ritchie] and our crew. Because it creates that environment where you can have fun and it's easy to enjoy the day... I think that's why we all get to shine in an environment like this."
