The death of actress Carrie Fisher still weighs heavily on the mind of her “Star Wars” co-star Mark Hamill.

Speaking at a “Star Wars Celebration” in Orlando, Florida, Hamill said that sharing memories of her with fans helps him cope.

During an hour-long tribute to Fisher, Hamill read from a letter he wrote just after her death.  In it he spoke about her intellect, her attitude and her sense of humour.

Fisher suffered cardiac arrest while on board a flight on December 27th from London to Los Angeles.

She died four days later at the age of 60.

Also at the Orlando event on Friday, the first trailer was previewed for the latest “Star Wars” film, “The Last Jedi.”
