This trick requires a turbo controller. (found one for about $25 on amazon compatible with PS3 and PS4).
Like most fighting games, there is a way to spam X and cheese to get trophies that are a grind.
What I found useful is setting button control X to LK+RK and setting a free button like R2 or L2 to LK (LP, RP, LK, and RK have to be set).
Choose someone that has a continuous power move like Jun or Asuka (both who I play with) and rubber band down X once you get turbo going.
Leave it on overnight and you should be set for the Tekken Lord trophy and the Movie Buff trophy.
