Famously gravel-voiced US actor Vin Diesel is among a rather large list of actors we'd like to see and hear on helium (Al Pacino is another), so you can only imagine our delight when we discovered this morning that Diesel was actually given the helium treatment when he appeared on Jonathan Ross' talk show a couple of years back.
The line Vin comes out with, "if I medicined you, you'd think a brain tumour was a birthday present", is a quote from Withnail & I. Kudos Vin Diesel, kudos.
