Populate a ComboBox

[zplugger]

Trying to change a textbox over to a combobox,thetextbox does a data search to find a name. I hope
a combobox would populate with more of the same names then narrow down to one. So if there was
six Jims it would show all until last name is typed in. Here is the code for the textbox all I changed was the textbox to combobox. Not
sure how to populate the comboBox? Attached is a workbook of what I would like to do.

Private Sub ComboBox1_Change()
 Dim arrList As Variant
    
    With Me.ListBox2
        .ListFillRange = vbNullString
        .Clear
            
        If Range("AB2").Value = True Then
            'Search by Actor
            arrList = Filter(Application.Transpose(Evaluate("if(isnumber(search(""" & Me.ComboBox1.Text & """,list_actors)),list_movies)")), False, False)
        Else
            'Search by Movie
            arrList = Filter(Application.Transpose([list_movies].Value), Me.ComboBox1.Text, True, vbTextCompare)
        End If
        
        If IsArray(arrList) Then
            .List = arrList
        Else
            If InStr(1, arrList, Me.ComboBox1.Text, vbTextCompare) Then .AddItem arrList
        End If
    End With
    
    If IsArray(arrList) Then Erase arrList
    If ListBox2.ListCount <> 0 Then
        ListBox2.Selected(o) = True
    Else
        Range("J9").ClearContents
    End If
    
End Sub
