Ice Cube has told RTÉ Entertainment that the best advice he received at the start of his career - and which he still swears by - was to "sign your own cheques".
Matters fiscal are very much part of the rapper-turned-actor's latest role in new film The High Note, which sees him playing Jack Robertson, the manager of superstar singer Grace Davis (played by Tracee Ellis Ross).
"To this day I still don't do any online banking!" he smiled. "I don't trust it! I still want to sign cheques!"
When asked if Jack was based on everyone he had ever met in the music business or one person in particular, Ice Cube replied: "He's taken from a few guys. It's all kind[s] of managers, just like it's all kind[s] of artists.
"Some managers, you know, are the quiet guys who don't even want their picture taken. And then there's some guys who wish they were the star! They want to be out front! They don't care. And if they had the talent they wouldn't even need to recruit talent! That's the kind of guy who's fun to play. He's dressed like he's going to the Grammys every day! It's just kind of cool to be Jack!"
Ice Cube said fans' biggest misconception about their favourite stars is that "we're having fun all the time".
"That it's not real work," he continued. "It's fun to get up there and perform sometimes; most of the time it's work. Because you can't just have fun; you've got a responsibility to entertain people, make sure they have fun.
"If you have too much fun and you're not on point - you're not tight, you're not entertaining, you're too loose - you defeat the whole purpose. I stopped doing shows on New Year's Eve because everybody was drunk except me!"
The High Note is available to rent at home now.
