It depends what you mean by "start," as Michael Caine (whose name isn't even really Michael Caine, but rather the more ponderous Maurice Micklewhite) took the long, hard road to acting success.

His true start was on the stage, as is the case with so many British film greats, but his breakthrough to fame came in a quick succession of film hits in the mid-1960s.

Award-winning Icelandic composer Atli Orvarsson's music was all over "Chicago P.D.," and indeed all over Dick Wolf's other two "One Chicago" properties ("Chicago Med" and "Chicago Fire"). At least it was until recently. He's still being used on "Med," but he disappeared from the other two in early 2018.

"Deep State" has not been canceled, but Mark Strong has.

It's become something of a trend among prestige dramas to write out their seemingly unkillable main characters (see, for example, "True Detective," "Fargo" and, of course, "Game of Thrones"). Nonetheless, it still came as a surprise to fans when [slight spoiler alert] Mark Strong's character seemed to have been written off at the end of "Deep State" Season 1.
