The man behind 007 hit the headlines in October when he said that he'd rather "break this glass and slash my wrists," than play Bond again.
His remarks sent shockwaves through Hollywood as bloggers and editors alike started speculating about his successor, reported Contactmusic.
But Fiennes, who plays Bond's boss, M, in new film "Spectre" feels confident Craig will be back, insisting his castmate's negative comments were just the result of fatigue.
"Daniel is filming for something, like, seven months and he's in virtually 95 per cent of the film and does all his own stunts," Fiennes revealed during an appearance on US talk show "Watch What Happens Live".
Craig made his debut as 007 in 2006's "Casino Royale". He has also played the suave superspy in "Quantum of Solace" and 2012's "Skyfall", the most successful Bond movie in franchise history.
