The first thought would be that Alan Rickman is the link because he starred in the original Die Hard (as Hans Gruber) and in Love, Actually (as Harry), but he did not appear in 1984's Gremlins. The link would have to be Christmas. Die Hard involves Officer John McLean who is in town to celebrate Christmas with his kids and estranged wife. Gremlins involves a Christmas gift that ends up being more than anyone can handle. And Love, Actually follows the lives of several couples in the weeks leading up to Christmas.

Assuming that you are talking about Die Hard 3: Die Hard with a Vengeance, that was Samuel L. Jackson.

In "Die Hard" (1988), Reginald VelJohnson played Sgt. Al Powell.
