Reynolds and Fisher were buried together at Forest Lawn Cemetery on 6 January, where the ashes of the Star Wars actress were carried in an urn shaped like a Prozac pill.
Fisher had spoken publicly about her battle with bipolar disorder and drug problems during her life.
Following the funeral, Todd Fisher promised a bigger service down the road for the public and all their other friends.
Explaining the choice of urn for his sisters ashes, he added: Carries favourite possession was a giant Prozac pill that she bought many years ago and she loved it and it was in her house. (Carries daughter) Billie and I felt it was where she would want to be.
We couldnt find anything appropriate. Carrie would like that, it was her favourite thing.
Fisher, 60, who shot to fame as Princess Leia in Star Wars, died on 27 December after suffering a heart attack on a flight from London to Los Angeles four days earlier.
Singin In The Rain star Reynolds, 84, died following a suspected stroke, a day after her daughters death.
