I pronounce saw withount an R, and sore with one.
But them Iām not a native speaker. My teacher long long ago tried to teach me british english, but it has probably drifted to US english mixed with german and dutch over the years 
On I side note: that movie is painful to watch. He really needs to sharpen the saw. It could go so much faster. I can still feel my arms from using the hand saw to cut down my firewood last week.
