This year's sequel 'Night at the Museum: Secret of the Tomb' may not be particularly notable as a special effects action comedy, but it's notable for containing Robin Williams' final performance, a third turn as a waxwork of Teddy Roosevelt brought to life in a New York museum. This time he travels to London for more antics at the British Museum.

When Williams died in August at age 63, he had completed his work on the film. So director Shawn Levy found it very emotional returning to the editing room after Williams' death. "It's sad, but I do feel in some weird way honoured to be serving this legacy of work, this legacy of performances of which this will be his last," he said. "It will be around long after him and long after all of us."

William's role in this third film is his largest in the franchise, and this was planned as the final chapter. "In saying a certain kind of farewell to this franchise, there are themes built in that are very poignant," Levy said. "So Robin's performance is already emotional, and I think the weight of the emotion that he brings to these final scenes will have added depth."

There is one more Williams performance to look forward to, a vocal role in the zany sci-fi comedy 'Absolutely Everything', which also features the voices of the 'Monty Python' team. It's out in February.
