Five Star Gift Ideas

How about a Benedict Cumberbatch themed gift basket? You could fill it with items such as:

1. A copy of one of his movies or TV shows, such as "Sherlock" or "Doctor Strange"
2. A Benedict Cumberbatch biography or autobiography
3. A poster, mug, or t-shirt featuring Benedict Cumberbatch's likeness
4. A book of his acting scripts
5. A Sherlock Holmes themed puzzle or board game

You could also consider gifting her a ticket to a play or movie he is starring in, or even a virtual meet and greet with him if they are offering them.

Or you can get her a star map with an important date you share.
