When a contract killer murders the wrong person, he must hire a body guard to protect himself from his own employer.

I agree with all of the above. The bodyguard steals the action and the hitman feels weak and passive.

I am interested in the bodyguard, if the body guard proves to be a complimentary character in a buddy movie. For example, in case of a comedy:

When a perfectionist hitman kills the wrong person, he must escape his mafia boss employer with the help of a haphazard bouncer.

OK, it probably is totally different from your intentions, but it's an example where the two characters compliment and contrast each other.

Otherwise, as long as the hitman is the protagonist, the bodyguard is secondary and should not steal the show.

Agree with Richiev.? ?It's better if the logline frames the plot with the protagonist having a proactive goal.? Hiring a bodyguard seems to put the bodyguard in the pivotal role, the key character in how the plot plays out.? The hitman comes off as weak,? appearing to hide behind the bodyguard.
