The Gospel of Luke is not yet available in any format outside the UK, as far as I know, but you can watch the trailer for it, which went online six days ago, below:
Note: The Gospel of John, which first premiered on Netflix back in December 2014, had narration by Brian Cox (KJV) and David Harewood (NIV), but The Gospel of Luke is narrated by Sir Derek Jacobi (KJV) and Richard E. Grant (NIV).
It is also worth noting that The Gospel of Luke apparently has a prologue that focuses on the writing of the gospel itself, whereas The Gospel of John had no such device. And one of the interesting things here is that the film shows Luke dictating his gospel to a scribe while reading other scrolls (his sources? other gospels, perhaps?).
The Gospel of John has been available on DVD in North America since October, but it was apparently not available in the UK until it was released alongside The Gospel of Luke last month. The Lumo Project posted a trailer for that DVD’s release, too:
The Lumo Project’s website says The Gospel of Luke will come to North America later this year, and it says The Gospel of Mark and The Gospel of Matthew will come out and complete the series on both sides of the pond before the year is up, too.
As ever, stay tuned.
