• When the relative pronoun (who, which, etc) is the subject of the relative clause, you do not need another subject.
✓ I admire Jude Law, who always works hard on his films.
✘ I admire Jude Law, who he always works hard on his films.
• Whom is quite formal. It is natural in informal English to use who instead of whom, even when it is the object of the relative clause. After a preposition, however, we always use whom. Informally, we usually put the preposition at the end of the clause and use who.
✓ Is that the man who we saw at the cinema yesterday?
✓ Charlie Chaplin was a comic genius to whom all comedians owe a great deal.
✓ Charlie Chaplin was a comic genius who all comedians owe a great deal to.
• Where can be replaced by a preposition + which. Less formally, we can put the preposition at the end of the clause.
✓ The theatre where /in which I first acted is somewhere around here.
✓ The theatre which I first acted in is somewhere around here.
• We can do the same thing with when.
✓ Do you know the year when /in which the first western was made?
✓ Do you know the year which the first western was made in?
