Rob Marshall says Emily Blunt was robbed during awards nominations.

The 'Mary Poppins Returns' director is livid that Emily did not receive any major acting nominations for her role in the update of the classic film and believes her performance will stand the test of time, according to The Sun.

Speaking as he picked up the Cinematic Imagery Award at the ADG Excellence in Production Design Awards, Rob said: ''Well, I will say that it was disappointing, there's no question, and I think people felt that.

''She really did the impossible by taking on this role and doing such extraordinary work with it.

''But I will say that after the soon-to-be-forgotten awards season, which will be a few weeks from now, her performance will last the test of time and it will live forever, because it's so extraordinary.

''And I will say Emily, like me, is a sort of very positive person and just sees that . . .  sees the good, sees what she did, sees how people are responding to the film and her performance, and that's what you really carry with you.''

Rob also claimed there is an unfair bias against musicals, saying: ''I don't feel that they're given the same weight or attention in a way as other films, because they don't feel as politically relevant.

''But to me, they're 100 times harder to make and what she did on this film was so extraordinary.''

Meanwhile, Emily looks set to play the practically perfect nanny again.

Director Rob Marshall has said another movie based on the books by P.L. Travers is in the ''early stages''.

He said: ''It is early stages, but I will say right now that there were eight books, so there's a lot of great material still to mine.

''That's what we worked from, those incredible eight books of P.L. Travers. So, you know...''

Due to there being so many novels in the series, Marshall has hinted there could be multiple films to come, which could see the franchise go on for as long as the 'Star Wars' and James Bond series.

He added: ''Listen, how many 'Star Wars' films have there been, you know what I mean? Or James Bond films.

''If there's a great character and story to tell, why not?''

Producer John DeLuca said: ''Emily does light up when she speaks to me about it. And if the people want it, I think it will happen.''
