How come Tyrese was in Transformers 3 longer than Megatron?

Megatron was like the leading villain...if u know what i mean. Megatron was only in the film for 3 minutes, but Tyrese had like 20 minutes +.How come Tyrese was in Transformers 3 longer than Megatron?Tyrese's character, Epps, probably had a bigger presence because it is more expensive and time-consuming to animate a computer generated robot as compared to simply filming an actor. In fact, in the second movie, the giant robot Devastator was so complex that it melted a computer processing it at ILM. Those complex robots are the reason why the Transformers movies have such gigantic budgets. In order to cut costs in an already large budget, the story had to be centered on humans rather than the Transformers.



Also, as DeniedbyFleury has already said, Megatron was not the lead villain in this movie, so the screentime was given to Sentinel instead.How come Tyrese was in Transformers 3 longer than Megatron?Good question, however Megatron was not the "Lead" villain in this installment. Sentinel Prime was.
