He explained how he likes to mix things up with surprising casting.
"I tend to do this every season, I like to do some casting that's a little bit outside the box, you know, from Stephen King to David Hasselhoff – we try to do stuff that's fun," he explained.
Manson's friendship with Sutter helped him land the role of Ron Tully, a white supremacist prisoner who Jax [Charlie Hunnam] uses to expand his power base.
Sutter said: "Manson, I became friends with through some music buddies, and he's a huge fan of the show and that was him basically just wearing me down and we found a great role for him and he's great."
Like Manson, Love was also eager for an SOA role. "We had this role of a school teacher and I thought, 'Who better than Courtney Love?' and so it sort of fits into our parameters of 'Sons of Anarchy' casting," Sutter said.
Season 7 premieres on Sept. 9 on FX.
