Sorry I meant I hadn’t seen/come across the advert before - but had watched the video posted here!
And of course actors in film, tv and on stage audition and then receive their scripts well in advance to learn lines etc.
But for this type of role, they may not necessarily know much before hand...
(School friend does voiceover and other similar work and know she’s been offered jobs where just turns up without much knowledge of what the job would involve. She has integrity though!)
Assuming it is her and not dubbed or anything else, MFW really looks and sounds as if she is reading from an auto-cue here - it doesn’t seem at all natural or as if she knows the script!
Maybe that’s just the very wooden “acting”?!
And I’m giving too much benefit of the doubt!
