They're both British, but I can't see Cumberbatch as Robert April, nor April having a BFG. Why? Orci and Kurtzman based their version of George Kirk on Diane Carey's, from her novels Final Frontier
(no relation to STV) and Best Destiny
- and in those books, Robert April was a pacifist. To the extent that when it came time to open fire on the Romulans, he chose to turn command of the Enterprise over to George rather than order the attack himself.
