The 'How Soon Is Now?' guitarist has frequently denied that he would regroup with Morrissey and their fellow bandmates in the 25-years since The Smiths split, but recently admitted to Rolling Stone that the idea of a new tour is intriguing.
"I don't know about the possibility, but what I do know is that I understand how great it would be to make so many people happy," Marr explained. "And the other thing I know is that Morrissey and I are so very different. Those are the only things I know."
Marr also denied that he and Morrissey rejected a $75m (£47.2m) offer to regroup for a 50-date concert tour in 2007.
"I have heard that - a few times. No official offer was ever made to me... But I did hear that, yeah," the musician said.
The star went on to say: "Nothing really gets off the ground just purely because of money. Certainly, as I see it, so many other things would have to be fixed and we're just too different to get them fixed, it appears."
Marr joked in March that The Smiths will reunite when the current British coalition government agrees to step down from power.
The Smiths released four critically-acclaimed albums between 1984 and 1987 and scored UK hits with 'Heaven Knows I'm Miserable Now', 'Panic' and 'Sheila Take a Bow'.
