"Robert Fetcher was once a household name," the anchor says. "But
what's become of him since? Behind this door lies the answer."

"Robert was the white Emanuel Lewis of his day," the film tells
us, "without the whole little person thing."

Duif Calvin gave us her take on this enterprise: "This looks
to me like a work by a new filmmaker who is heavily influenced by director
Christopher Guest. (Guest's films include Best in Show, Waiting for Guffman,
A Mighty Wind, and he was one of the writers and actors for Spinal Tap.)
As for why they picked a chess theme – why not? These kind of movies
start out with, "Wouldn't it be funny if...?" and then try to set
up each scene so that it's delivered with great seriousness by the actors,
but is supposed to be absurd to the audience. It's hard to do. Guest is very
good at it, but even so his humour is less universally accepted than a more
direct comedian like Jim Carrey or even Jack Black.
Andrew Bell of San Diego, USA wrote: "I enjoyed most
of Guest's three major "Mockumentary" films ("A Mighty Wind",
"Best in Show" and "Waiting for Guffman"). Of course, "This
is Spinal Tap" is the penultimate "Mockumentary" (posing as
a "Rockumentary") and will likely stay on its perch as such forever.
In that movie, Guest played Nigel Tufnel, the band's bass player, and gave
one of the best comedic performances I have every witnessed.
The Knight to F4 trailer gives the impression of a very bad film. The acting
is way over the top and the situations (being pepper-sprayed by a cop over
a race dispute, being slapped by a woman due to being too forward, a fat guy
bathing, the Emmanuel Lewis comparison) don't glue anything interesting together
and are all unfunny and derivative of much better work. It seems to be a good
premise ruined once more.
