This Robin Williams-lookalike is uncannily good at impressions

Gandalf tries to lead Matthew McConaughey, George Bush and Robin Williams to Middle Earth.

You can't beat a good impression and this guy is stellar at them.

Jamie Costa inpersonates Ian McKellen;s Gandalf as he leads an unlikely fellowship of celebrities including Matthew McConaughey and George Bush ino Middle Earth.

All of them are pretty spot on but his Robin Williams is perfect - and he even looks exactly like him.

Costa came to attention earlier this month with this inspired tribute to the man himself. The video has over 3.5 million views.

Spookily good.
