- Liam Hemsworth was originally cast as a sniper in The Expendables, but the character was deleted from the script and later recycled into Gunnar Jensen. Stallone, however, remained in contact with Hemsworth and promised him a role in a possible sequel.
- He has the similar appearance to the Character Piers Nivans from Resident Evil 6, in both look alike and skill set (both are snipers and die.)
