Details of the plot in the fourth Matrix film have been kept under wraps, so it is unclear how or why Neo and Trinity are alive and well again. 

Priyanka Chopra, Jada Pinkett Smith, Yahya Abdul-Mateen II, and Neil Patrick Harris, are confirmed to appear in the fourth instalment of the anthology. 

But Agent Smith actor Hugo Weaving revealed earlier this year that he would not be able to reprise his role due to scheduling conflicts, as he can currently be seen treading the boards in The Visit, at the National Theatre.
