Zeiss makes a 135mm f/1.8 prime, for Sony mount only (well, technically, Sony makes it in Japan under the supervision of Zeiss). Nikon makes a 135mm f/2 for their mount. Canon is the only manufacturer with two primes at 135mm. None of the 3rd party vendors (Sigma, Tamron, Tokina) make a 135mm prime.
For video, I hope you'll have excellent camera support - 135mm would mean a big effect from camera shake.
